Navigating the multifarious space of pitch class combinations is a wonderful journey that may be accompanied with different tools we've made. Plot a mathematically perfect Chroma Waveform of a sine wave pitch oscillations collections.

Or just explore the collections of all possible note combinations of chroma with the Chroma profile. Or construct any note collection with the Chroma Compass. And in case you'll need to organize all those notes in loops in time - that's what the Chroma grid is designed for.

There's another endless Chroma Roll that will plot the relative pitch class power for any incoming audio. The same data may help you see the pitch class content of any sound with the Chroma See.
