Reed instruments show fundamental frequency rising during note onset

Evidence

When considering the notes played on pitched musical instruments, timbre relates to those aspects of the note which can be varied without affecting the pitch, duration or loudness of the note as a whole, such as the spectral components present and the way in which their frequencies and amplitudes vary during the sound. … The onset and offset portions of a note tend to last for a short time, of the order of a few tens of milliseconds (or a few hundredths of a second). Changes that occur during the onset and offset phases, and in par­ ticular during the onset, turn out to have a very important role in defining the timbre of a note. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1454 (#qualifies, via linked claim)
