| A quick rejoinder to Ed, and a note about MIDI pedaling
If one has MIDI data from a live performance on MIDI instruments (usually keyboard, but there are also MIDI guitar and wind instrument controllers), one can gather information from "note on-note on" command, and thus obtain IOIs, as well as note durations (onset to offset time) and inter-note durations (offset to onset times). As noted in my previous post, the trick/challenge is sorting out which notes/MIDI events to chose as being "in the same melodic/auditory stream" and hence which notes to use for making these sorts of calculations.
And re pedaling: Pedaling data is in the MIDI note stream itself, as the pedal is used to control offset timings of keys/events that have been actuated (though control parameters can be tweaked in various ways). Essentially the pedal suppresses the MIDI note off command from any key that has been released until the pedal is also released--in essence, an electronic sostenuto pedal, not a damper pedal.

I can't seem to think of any paper that has done such measurements systematically. But I would caution that notated duration in music is fundamentally about onset-onset time, not onset-offset time. So, while studying midi renderings (or other notation-related representations) would provide an answer to this question, it would be of questionable value.The only way to get a reasonable answer would be to study audio recordings of performances.

Dear list, I’m trying to find papers which report measurements of two aspects of note duration in solo instrumental monophonic music (e.g., recordings of solo violin, cello, trumpet, clarinet, flute, etc. – not piano, guitar, or other instruments that can play multiple notes simultaneously). 1. The average duration of notes in a piece 2. A histogram of note durations in the piece Thus for example this solo cello prelude by JS Bach last about 4 minutes and contains N notes (anybody know?), so the average note duration in this piece is about N/240 notes/sec. If one could measure the duration of each note in this recording, then one could plot the histogram of note durations in the piece. Is anyone aware of such data for any solo monophonic instrument? Musical style doesn’t matter (can be classical, folk, etc.).
