For this question, download the following file: chords.wav. This file consists of five chords being played in sequence. Each chord consists of at least three notes. Below, there is one box correcponding to each chord. For each, enter a Python list containing the frequencies (in Hz) of each note in the chord, each accurate to within 1Hz.

Note also that we are computing some large DFTs here, so you may wish to use the FFT algorithm to compute them. We have provided one such implementation in lib6003, which you can import with from lib6003.fft import fft.

Frequencies in first chord:

Frequencies in second chord:

Frequencies in third chord:

Frequencies in fourth chord:

Frequencies in fifth chord:
