The Solar Harmonic Spectrum Sets are a complete octave scale from Low C to High C. They are essentially the white notes on a piano. The Sharp Sets are the half tones in-between, which are the black notes on the piano. When you combine the 2 sets, you get a complete 12-tone chromatic musical scale in Pythagorean tuning. Every musical interval is therefore possible when working with the complete set.
Both sets are available in either Standard or Weighted.
