All the bins associated with a given spectral peak. Fully distinct peaks
are easy to deal with (e.g. a simple periodic tone). I have never got
around to writing serious peak-tracking things - unlike Victor, say,
whose partial-tracking opcodes will depend on it. It's definitely not
something to under-estimate! A primary application of transient analysis
is to avoid shifting bins associated with the transient itself (e.g. the
drumstick impact) and shift only the pitched bits. Short FFT sizes do
not help. So no free lunch, sadly! That's about as far as my knowledge
extends, pitch-shifting-wise.
