Analyzing Musical Structure with the Spectral History Ribbon
This is the spectral display of a highly dynamic and melismatic vocal passage. The music that this passage is taken from is part of the North Indian
classical tradition. This particular piece is performed by female voice accompanied by sarode drone.
The relative power of overtones to the fundamental along with the initial transients of a sound determine its timbre. The Spectral History ribbon is
very good at clearly displaying all of these characteristics. As a result, the spectral history is extremely effective in precisely identifying the features
which differentiate a truly superlative timbre from a mediocre one.
This is the fundamental of the female voice.
This is the second harmonic.
This is the third harmonic. Note that there is more power in this
overtone than there is in the fundamental or any other harmonic.
This is an explosive tension building passage. The timbral effect
created by the strong third harmonic in the voice reinforces the
musical gesture.
These are the upper overtones of the voice.
Option clicking on the zoom buttons increases or decreases
the number of data points used to compute the FFT for the
Spectral History ribbon.
Option clicking on a spectral feature causes the details
readout to display the precise frequency range that the
selected feature occupies.
This area represents the sarode drone accompaniment.
