You will use the spectrogram to identify features in signals whose spectra vary with time, including a brief guitar solo and synthetic signal composed of a chirp and sinusoids. You will learn about the tradeoff between temporal resolution and resolution of features in the frequency domain by changing the DFT length used by the spectrogram.
