I suspect the geometry, physical structure of one's own hand, and choice between right- and left hand. The thumb and middle finger constitute the two strongest digits (with the thumb being the strongest of the two), and it is debatable as to the order of strength of the remaining three digits. It is comparatively difficult for even experienced pianists to play with consistent note-on velocity (*), because the strength of each finger varies depending upon which digit is playing a given note. I've not seen a study of this and I'd be interested if anyone has knowledge of a well tested study of this sort, particularly (surprise) for piano.
HOW TO MAKE A REALISTIC PIANO IN PIANOTEQ 5 PROFESSIONAL
Which is why 127 levels of MIDI volume probably is about as accurate as even well trained ears need.Īs for actually playing more that 127 different volume levels accurately I am certain I can't (which i saying very little), but I'm again dubious even a professional can play consistently with that level of accuracy, let alone more. I tend to go with 1 dB as about a typical difference you can tell, and in a range of 120 dB that means 120 levels of sound. Studies say we can discern between about 0.25 dB and 3 dB although below 1 dB the results seem to be for special circumstances rather than more general sound. My takeaway from that stuff is that we can hear in a range from about 0db to about 120db (even this is unrealistic for normal music listening peaks - most places would shut down a concert hitting those levels). Here's a link to a page discussing ( in some depth ) the ability of humans to tell different sound volumes apart (amplitudes more accurately) : I'm doubtful a double blind test would show any real ability to differentiate. I'm extremely dubious that most people can, although I suppose those blessed with a well practiced and naturally precise ear for audio might be able to.
Ask yourself if you can honestly tell the difference between standard levels of 63 and 64 velocity.
