Berkshire Tapes have available a sam- pler of their offerings for the modest price of $1.50, which is less than the cost of the raw tape, This tape is similar in nature to those offered by the disc record com- panies for a much lower price than their usual LP record.

Brahms was highly dissatisfied with his
D -minor concerto and vowed. after its pre- mier,
"The next one will sound different."
Twenty two years and 68 compositions later it appeared, and it was different. Different than any previous work for piano and or- chestra by any composer.
Because of its major proportions. four movement form and the apparently minor role given to the solo instrument, it has often been referred to as
"a symphony with piano obligato." Perhaps so with a pianist of lesser abilities than Mr.
Rubinstein, but here the piano is of the master, dominant permitting the in the hands orchestra to share the score, but no more than that.
Together the pianist and conductor com- bine their understanding of the composer's intent to produce a work of the first mag- nitude. This together with RCA's superb sound is cause to label it as a major record- ing, a fact to be considered when building your basic tape library.
C- minor, Opus
NBC Symphony Orchestra
RCA VICTOR CC
Although the critics do not agree,
I feel that here is the definitive interpretation of this work in our time. And, speaking of our time, let me point out to those who are inclined to doubt the productivity of men past forty, that Brahms was past forty when he produced this First Symphony and
Toscanini was in his
85th year when he recorded it! a
Toscanini conducts this recording with drive and brilliance that is unmatched in any other recording of the work. The "old man" takes hold of his orchestra at the out- set and doesn't relinquish his control for as much as one semidemiquaver throughout the entire work.
\s no were challenged in every recording to meet
Toscaninï s speci- fications, have made this one of the very best.
I don't imagine that there will be a better recording of Brahm's 1st to come along for quite some time.

The conductor is conducting, the musi- cians are playing their very best but, at its best, the music is not George Gershwin.
At least, not to my ears it isn't.
The ques- tion is, why not? The orchestra plays well, the conductor has been applauded in this column for other things and the recording is excellent, so what happened?
My guess is that Gershwin's music is so idiomatic that when it is given a literal interpretation it becomes pedestrian. Gersh- win is so
American ican mind to that it takes the Amer- interpret (or appreciate) him.
This theory is somewhat substantiated by the fact that the "Porgy
Bess" suite, arranged by
Robert Russell Bennett fares better because here only the thematic mate- rial is
Gershwin's, the score is

The trumpet concerto displays an amaz- ine amount of virility in its construction as demonstrated here by Wobitsch and Heil- ler.
The trumpet is flawlessly presented by the soloist and recorded better than most
I have heard. It has a clear, natural sound without any of the piercing effect so often encountered in recordings of the instru- ment.
The orchestra and soloist are well pre- sented, with good balance and chromatic control. In short, I don't believe that it could he done much better.
The horn concerto comes off fairly well. although the horn is not as well recorded as the trumpet. The balance between or- chestra and soloist is about the same in both concerti.
The two Bach concerti are a positive delight to the ear. Heiler conducts Bach with a firm hand and pulls more from his www.americanradiohistory.com

The solo instruments are back far enough so as not to be overpowering when alone, yet are in evidence during orchestral tutti.

Miss Bianca and the orchestra get as much out of the second movement of this work as
I have ever heard.
A sentimental and understanding approach that thorough- ly charms the listener.
The third movement keeps pace with the style set in the second, but the first finds some complete little disagreement between piano and orchestra. Perhaps not re}-earsed as well, it does not impart the feeling of unity and rapport that exists in the last two movements.
I find that the balance between piano and orchestra, and sections leaves in the latter, nothing to be desired.
The record- ing is clean and crisp. but with a slight hiss present unless the treble control is shaded a bit; on my copy, at least.
The minor faults mentioned should not deter anyone from getting the recording, as there aren't any better interpretations available at this time.

Stabile's work as
Giovanni is not what one would expect to hear in a title role.
True, he is identified with the role through his performances at
Milan's La Scala, so perhaps he should be seen in performance to Bain an understand- ing of his apparent lack of control in this recording.

The rest of the performances on this excerpt recording are quite good but the most outstanding things about the entire reel are the recorded sound and the en- thusiasm of the performance. The dramatic interpretation of Hans Swarowsky is ad- mirably enhanced by the clean, clear and chromatic sound.

It is, however, an excellent tape and we were happy to have the opportunity to review it.
Anda delivers a sensitive and interpretation.
I would say that the performance is, to date, my favorite, par- ticularly the second movement, performed with infinite beauty and understanding of the composer's intent.
The orchestra and soloist are perfectly balanced and, together, deliver a definitive masterpiece that will last for some years to come.
Joseph de Pasquale,

I like it.
For the average music -lover the symphony's principal ap- peal has always been an emotional one and this recording arouses the emotions, as do few others, no matter how cynically you approach it.
Sound system demonstrators, particularly those with the mammoth speaker rigs, should watch their volume when first play- ing this tape as the bass is quite lusty.
If the volume control is too high during the quiet opening passages, the uninitiated literally jump out of their shoes during will the sudden, dramatic crescendo in the middle of the movement. The third movement will also cause labored breathing and twitching hair follicles under certain circumstances.
Because of its universal appeal to both music -lover and high fidelity fan,
I feel that Berkshire has produced, in this record- ing, a solid hit.

BALLADS OF THE
CIVIL WAR by Hermes Nye with Guitar
This is a
Folkway's production that is as visual as it is aural.
With the reel comes a
-page booklet containing not only the words to the ballads but a great deal of in- teresting historical background as well.
Hermes Nye, an attorney by profession, is an engaging singer from Dallas who handles these songs in an authentic manner that will hold the listener spellbound throughout. included in the collection is a ballad,
"Davy Crockett." not the one that drove you mad a few months ago, but one that was making the rounds in about 1836. It has to do with a fight that Davy had one day
(lasted a day and a night) and is filled with
19th century Tennessee colloquialisms that arouse many a chuckle.
If you like the current hit song, "My
Bonnie Blue Belle," then you may he in- terested to know that in its original, unex- purgated version it was a rousing song of secession.
In all, a successful recording and one that is a must for folk music collectors.

WE'RE back again Teen -Tapers, and more enthused than ever. I've heard from a number of you since the last issue, and it's great to know that you have interest and en- thusiasm for that's the most important item.
Last time we said that we'd talk about start- ing some school recording clubs so let's get right at it.
We feel that one of the best ways for teens interested in recording to become more ac- tive is to start a tape club at school. I've started one at my school and it's going along great, and there's no reason why you can't do the same thing. Briefly, here's what it takes.
First we assume that your school either owns or has access to a tape recorder, some tape, and a microphone. The only other things needed are some interest and a little hard work to start out with. Now, contact the person in your faculty who would most likely be interested in this project. Likely people are, audio -visual directors, science teachers, speech teachers, or any other in- terested teacher. Once you have this faculty member interested you have a great share of the work done.
He can stir up interest and get the cooperation of other faculty members. He can also help with another im- portant thing, getting permission to operate the club. Now you're set to call your first meeting. to
Get an enthusiastic announcement made the effect that a new, different, and inter- esting group is being formed for those stu- dents who are interested in tape -recording, radio broadcasting, dramatic reading, tape correspondence, and so forth. At the first meeting your big job is to retain the obvious interest in the group shown by those who attend.
Throw some suggestions out for discus- sion as to what the club could do around school both for fun and for school service.
Some ideas are: learn how to operate equip- ment and make good recordings; make a memory album of interesting events (a sort of yearbook in sound); produce taped radio programs for broadcast throughout the school; exchange tapes with schools through- out the country and world; provide record- ings for departments of the school.
With these suggestions you'll be surprised at the interest you'll start up and before you know it the members will have many more ideas of their own and will be very anxious to get started. At this point, you should end the first meeting on a high note of enthusiasm, and make plans for the second meeting at which time the club will really get organ- ized.
At meeting number two, we really get rolling. An election of officers is in order, and all necessary action is started to get the club officially recognized. In my school, per- mission must be obtained from the student council after a charter is drawn up. Once the president is selc.tc,'.
should be opened as to just what areas the club wishes to specialize in, be it general record- ing, radio broadcasting, tape responding, or what have you.
This choice will govern your actions.
Whatever you choose you should make immediate plans to start at it right away. A lot of discussion will cause the members to get bored, while imme- diately starting out on a project will bolster interest.
If you're going to broadcast, plan a show; if you decide to begin a memory album, pick out the next important event coming up and plan to record it.
Also plan on having the audio visual di- rector, principal, dealer, or some one else well versed in recording, drop around at your next meeting and give a demonstration and short course on recording. Since your activities center around recording, this is very important.
There you have the basic idea.
We've told you how to set up the organization, and get started. Once you're started you'll naturally proceed along your own special interests and can have as much fun as you care to provide for yourself.
Teen- Tapers is here for you and to help you we with your interests. All through the year will be giving to you suggestion aids and projects.
We'll exchange ideas, and answer your questions. in the
We have planning right a number of things now. In short order, we'll have the official
Teen -Tapers Club charter, and membership cards ready, as well as a detailed outline on how to oper- ate your club. Tape Recording is also going to offer us a special Tape Club group scription rate.
Once you have your sub- dub planned or organized, let us know about it so that we can include your group as an offi- cial
All Teen -Taper Clubs will be requested to write to us telling of their activities so we can compare notes. Outside of the op- portunity of exchanging ideas, the services of Teen -Tapers column, the reduced sub- scription rate, and the opportunity for meet- ing other tape clubs around the world, the clubs will be independent and unrestricted.
How about it? Sound interesting? Get going now and start a tape club among your schoolmates and when you do, be sure and let us know so you can become a member of our group.
We want to take a minute here to thank those who dropped us a line. Alan Caruba, down at the University of Miami in sunny
Florida, says the column looks interesting to him. Garry
Ball, at the University of
Nebraska Ag school, writes to tell us that when some of these clubs get going the radio station at the U will be glad to exchange tapes.

T. Z., Micco,
Certain types of oscillators in TV sets do radiate a signal especially in the region of 15,750 cycles per second. We are unable to say how it is getting into your radio but we rather suspect it is travel- ing the power lines. We would suggest that you try a
"brute-force" filter on the

this is the cause of the trouble. The sweep circuit of the set

TAPE RECORDING, Severna Park, Md.
The uses varied of a recorder are but here is a use that many and will be new to many of the readers of
TAPE. RECORDING magazine. This subject is one which a few years ago was many laughed off as a joke.
Today thinking people including scientists, find much food for thought in this study.
It is the study of flying saucers.
Thousands and thousands of sightings have been made, many books have been written about it and flying saucer research up all over the groups have sprung world. This may seem like science fiction to many but they have not studied the vast amount of material that is rapidly accumulating.
In California there is a
Adamski who has written two books on flying saucers, the first entitled "The Flying
Have Landed," and the second, a new book, "Inside the
Ship," in which he relates message the startling experiences of meet- ing the visitors in from outer space and riding their space ships. He brings a wonderful from the space people to the earth people.
Of course this has caused a great deal this of controversy and criticism.
Much of criticism has been directed against these books and

To lick the problem, the engineers installed the designed governor which permits a very wide fluctuation in

Plane cabins present unique, and tough acoustic prob- lems.
noise level in aircraft, for example, is very strong in the bass- baritone register and the sound absorbing ma- terial in the cabin not only soaks up the noise but the music as well.

They have discovered that music must have a tonal range much greater than the noise it competes with so

Both respond to the same treatment; a series of instructions in good English.
Anyone who has both a dialect and a tape recorder should be able to correct the former with the help of the latter, says Miss Fogler.

Miss Fogler uses three methods of recording a student's voice for study and practice; first, reading; second, mono- logue; third, conversation. There is no singing, though the musical scale is sometimes used in "toning," with no notes being spoken. Rather a humming of the musical scale with the mouth open.

A variety of microphones controlled

Although several of the mikes were of good quality, others were not, and the quality of recording varied as the various mixer control settings were changed.

The orchestra may even acquire a slight roomy quality which will not only eliminate any
"canned music" aspect in its tones, but should also create the illusion that the or- chestra is playing in a hall larger than the one it occupies.
In this way some of the detrimental effects produced by the mismatch of the orchestra to its surroundings can be partially if not completely remedied.
This leads us directly to the subject of room simulation.
There are times when you may not want to correct defects caused by the wrong type of room, but rather to simulate completely different surroundings in order to make the orchestra fit an imagined room. For instance, you may want to create the effect of an orchestra in a small live room.
One way to do this is to set the instruments very close together and then to hem them in from all sides by large smooth wooden panels. Such hard surfaces will readily act as reflectors for the various tones of the instruments and will thus duplicate the "canned music" aspect of a small live room.
If a small dead room is required, then you can hang thick drapes over the panels, place rugs under the instru- ments, and even hang sheets of linen, awning- fashion. over the whole orchestra.
By using these or other sound absorbing materials, you should be able to reduce echo to a
the orchestra will seem to be playing in a small, completely dead room.
just as you may have wanted to shrink a large room to make it sound like a small one, you may also want to blow up a small room into an auditorium. One

10 feet with the faces tilted toward the musicians. Below: note the drapes hung from the balcony and sound screens to absorb reverberations which might mar the recording.
Making a room seem smaller than room but with the microphones it is by using two microphones close in to pick up the strings.
The same set -up can be used in a small farther back, to simulate the singing sweep of the strings as would be heard in an auditorium. way to create this illusion is to introduce a pronounced echo artificially into the orchestra pick -up.
This is done by means of a second microphone which can be located anywhere in the set -up, although preferably as far as pos- sible and facing away from the orchestra microphone. Now all you have to do to produce the desired echo is to open this second microphone while the orchestra is being picked
directly on the first unit.
As the tones of the various instruments will strike both microphones at different times, there will also be a time lag between the dual pick -ups of each mally tone. This, plus the slight feedback which will nor- occur
the two microphones open at the same time, will produce reverberation on the recording which will closely imitate sound bouncing around a hall or audi- torium, particularly one not very well soundproofed. And since the larger the hall the more echo it will have, you can control the simulated size of your recording room by in- creasing or decreasing the amount of sound picked up by the second microphone. You can create an even more
of room size by changing the dis- tance between the two microphones so
the time lag of the echo introduced more closely duplicates that of the room being imitated.
A second means to create the illusion of room size on a recording is the echo chamber.
Briefly, this device consists of a series of connected corridors like a labyrinth with a loudspeaker at one end and a microphone at the other ex- treme. Sound picked
on the regular recording micro- phone is fed from the external speaker
of the re- corder into the loudspeaker in the echo chamber.
sound waves travel along the corridors of the chamber and are picked up at the other end by the microphone. The sound from this last microphone is mixed with the sound picked up by the original pick
-up unit and
combined tones recorded. Here again the delay incurred by the sound travelling through the echo chamber corresponds to the time lag of an echo in a large hall.
You can make an acceptable echo chamber by placing the loudspeaker and microphone at opposite ends of any long hall or corridor, particularly one that has smooth walls and uncarpeted floor.
In a pinch you may also use a bath room with its hard reflecting surfaces.
By changing the relative positions of the loudspeaker and microphone in the echo chamber you can readily vary the reverberation time and thus reproduce the effect of rooms of different sizes. You can obtain even finer con- trol by varying
the volume of the loudspeaker or that of the microphone input.
As a live room will produce a louder echo than a dead or sound- treated room, chang- ing the volume of the echo, will also change the simulated
of the room. Thus by introducing the correct amounts of time lag and volume, you can make your re- corded orchestra sound as though it were playing in a room of any desired type and size.
All these are tricks of the trade which you can use only to to distort orchestra pick
-ups for mere amusement, important, to match the room to the orchestra so that
create legitimate effects for dramatic scenes and. most
best recording can be obtained under the particular cir- cumstances.
The small, round microphone that came with my
Compact" recorder was inconvenient to use because it could not be adapted to a standard mike stand. Consequently,
I made a wood stand which serves the purpose very well.
The construction of the stand is very simple, consisting of three parts: the holder, the stem and the base.
If you care to make one like it, follow this procedure:

Jim Greene, new secretary of Tape Respond- ents,
Tape Respondents, International has a new executive secretary in the person of
Jim Greene, who hails from Little Rock,
Arkansas. Jim succeeds Fred Goetz in this capacity. Fred regretfully resigned due to failing health, and has been re- admitted to a San Francisco hospital, never having fully recovered from a serious operation in 1954.
His illness has prevented him from answer- ing a considerable amount of mail, and we are sure all members will understand the unfortunate delay in receiving a reply.
The new secretary expects to get T
-I back in full swing within a short time, and plans to catch up on back correspondence as soon as possible. There will, however, be a short further delay, necessitated by the trans- ference of all dub records from
San Fran- cisco to Little Rock. Meanwhile, anyone wishing to contact
Jim may write to
Box 21, Dept. T, Little Rock, Arkansas.
Jim requests that any
-I members whose addresses have been changed since the last membership roster was issued notify him immediately in order to incorporate the changes in the forthcoming 1956 roster.
Ed Bush and daughter,
Gloria, behind counter of Club exhibit at the recent Indianapolis Hobby
An exhibit for
Tape Pals, prepared member
Bush, was presented at the
Indianapolis Annual Hobby Show, which ran for nine days beginning November
He was assisted by his wife,
"Jerry," his daughter, Gloria, and fellow club mem- bers, Hal Fisher and Paul Bonham.
Ed, an estimated 9,000 vis- itors listened, through headphones, to folk music and specially arranged tapes from 20 countries, containing songs and messages from local residents in each land.
Twenty hours of visitors' comments were recorded by Ed, via a lapel mike worn neck- lace fashion. When edited, these will be about three hours long.
Ed was interviewed by radio station
Collins, regarding a program concerning tape exchange. He was also in- vited to record a Ladies' Day program of the Rotary Club of Indianapolis, which they wished to send to Rosebud Australia Rotary in an exchange of tapes.
Ed successfully carried through this invitation on Decem- ber 6, 1955.

The same may be said of its performance.
612 is available in two forms, one, the portable type which is shown above and which is contained in three matching Samsonite cases and two, in the matching wood cabinets shown on the facing page.
There are no words to describe stereo sound, you simply have to hear it
-it is an experience. There is no question in our minds that the serious music lover who has gone as far as he can with his hi
-fi system and records is going to switch to tape and stereo sound in droves.
This Ampex outfit is not inexpensive but to make the

have $700 to
all at one time the company has instituted a time payment plan through its deal- ers.
Actually, stereo sound itself is not new but only now has it become practi- cal since the advent and growth of the
tape industry in rector years. For stereo, tape is the only logical medium.
The 612 and its accompanying am- plifier- speakers are of the best crafts- manship and show evidence of quality control in the factory. All are well and carefully made.
The controls and threading are such that even a child could operate the unit.
The feed reel is at the left and the tape simply passes from it, across the heads, between the capstan and roller onto the take -up reel.
Two levers control the play modes, one for play and ward and rewind. the other for fast for-
At the other end of the tape deck are the selector switch for either single track
stereo and the volume control.
Two heads are mounted under the shield, the one at the left being used to pick up dual and full track signals and the one at the
to play the in -line stereo tapes.
In a recess on case are the side of the 612 the plug for the 110 volt line and the two outlets for the left and right speakers.
These are marked left and right so that the user will be sure to have the
sounds coming from proper speakers.
If the leads are re- versed, the orchestra is likewise reversed left to right.
we like very much about this outfit is that the master volume control on the tape trols equally

also appreciated the fact
the two speakers were matched. Once the controls have been set on the
and left individual speakers all volume adjustments are made with the single volume control on the tape phono- graph. Anyone who has ever tried stereo sound using two different speaker sys- tems, each with its individual controls will appreciate this feature as we did.
The connecting cables are of gen- erous length and will take care of most set -ups. Shielded wire is used and should longer cables be needed they can easily be made up. A standard plug is on one end and a cinch phono plug on the other.
The model 612 machine has a re-

is rated at 1.25 volts into a load of 100,000 ohms or more at program level. This is enough to drive any standard power amplifier.
If the home already has a high fidelity music system, the 612 can be added to play the stereo tapes provided another power amplifier and speaker system matching the existing one, is added to take care of the second channel.
The placement of the speakers in the room is of importance. The basic
ciple is to have the sound seem to come from between the speakers. The speak- ers should be placed straight out in the room, not facing toward each other and the use of corner horns is not advised.
The maximum size reel the machine will accommodate is the standard
