Five instruments, one band. Each row is a real EEG "instrument" playing at its own speed. Drag the right band name onto each waveform — fastest at the top, slowest at the bottom, just like a real spectrogram's frequency axis.
↑ Faster / Higher Frequency
↓ Slower / Lower Frequency
Delta through Beta, all five instruments identified by ear. That's exactly what a spectrogram does automatically in Chapter 3's lab.
