Drum notes focus more on elements, rest and rhythem, while piano scores focus more on scale, melody and chords. But both instruments use five-line staff for notation. I use digital DAWs for song-writing, I almost couldn’t read any notes or music sheets now. Digital shortcuts and interfaces almost convert my cognition and I see almost all instriuments as signal-generators now. So I started research, redesign and explore more possible ways to represent drum patterns.
