This Instrument Will Register Body Reactions of Student Piano Player (Nov, 1929)
I can’t imagine how this would help teach the piano. I think Dr. Johnen just got his kicks by strapping women into weird equipment.
This Instrument Will Register Body Reactions of Student Piano Player
A NEW device has been patented by Dr. Kurt Johnen, Berlin piano pedagogue, which records the motions and bodily reactions of a piano player to determine if the selection is being properly interpreted. A lady is pictured being examined by the device. A pneumatic belt records the change of the circumference of the chest, pneumatic cuffs about the upper arms control the changes of muscle tension, through a hose is recorded the rhythms of respiration and another hose transfers the strength of touch. Dr. Johnen expects this device will aid him in instructing his pupils in interpretation.
Electricity Runs New Player Pipe Organ for Home (Oct, 1931)
“Compact” is not the first word that comes to mind when I look at this picture, but I guess compared to most other pipe organs…
Electricity Runs New Player Pipe Organ for Home
Designed on the principle of the player piano, a compact new pipe organ for home and school plays music automatically from a flexible roll. Because of its unique feature, the “reproducing organ” will bring into the home an entire symphony, which, if played by hand, would require the services of a whole group of artists. All of their movements may be recorded upon a single roll. The organ is expected to be of especial value in schools. Pupils of music appreciation classes are enabled to hear the compositions of masters played by famous musicians and recorded for the purpose. Electric mechanism works the instrument.
