Saxophone vs. Sarrusophone (1)

Saxophone vs. Sarrusophone (2)
Little did he know that “jazz”was about to become one of themost successful music universesof the twentieth century, openingthe path of success for theSaxophone
Again, the success of this instrument cannot be ascribedsolely to purely functional reasons (otherwise theSarrusophone would have made it too)

Alphanumeric Keyboards (2)
Old style mechanicaltypewriters have oftenbeen (ab)used by musiccomposers in manycontemporary musicworks (Cornelius CardewScratch Orchestra, forex.)
That is: they considered the typewriter playable, and theemitted sound results musical

So?
All these examples (and many more can be found), outlineone essential issue:

The Conjecture (1)
Proper physical impedance matching is what ac-tually makes the difference between a successfulmusical instrument and a non–successful one.

The Conjecture (2)
The impedance of the instrument must be tuned to thecapability of the physiology of the specific body part orparts that are involved in playing it (fingers, lips, arms,mouth, etc.)
The result is the ability to learn to be extremely fast andprecise in playing by calibrating the exact balance of forcesrequired by the performance

The Conjecture (3)
Possibly, these “regions of matching” behave in a more orless linear way, while their boundaries becomesubstantially non-linear
And it is precisely this non-linearity that makes up for an“extra” expressive touch in many cases (think of“over-blowing” or “flautando” playing, for example)

Conclusion
Proper impedance matching (which seems to be also amore general basis for enaction) between local humanphysiology and musical instruments is possibly a goodmotivation behind the success of musical instruments
How to study these “mapping areas”? Can asynthesis–from–analysis method be devised?
Please note: in contrast with all the trends in interfacedesign and HCI, musical instruments are hardly designedto be “friendly”; rather, they are designed to achieve thebest fit with a highly skilled human physiology
