Additive & Spectral: Partial Tracking
Partial tracking is the process of detecting single sinusoidal components in a signal and obtaining their individual amplitude, frequency and phase trajectories.
Monophonic Partial Tracking
A short term Fourier transform segments a signal into frames of equal length.

For every STFT frame, local maxima are calculated in the range of integer multiples of the fundamental frequency.
