Supernovae can be seen visually. So what extra does spectroscopy do? Is it that spectra of supernovae can be used to classify them, in a similar way that spectra of stars can classify the stars into certain spectral types?

When a stars goes supernovae, is there a change in spectra (composition wise) before and after?
