From The Music Notation Project Wiki
I am particularly interested in how 6-6 alternative music notation systems make interval patterns clear and consistent. This will contribute to learning to improvise and play by ear, along with many other benefits.
I designed TwinNote Music Notation, which is my preferred notation system. It is largely based on Twinline, an earlier system that also used different notehead shapes to achieve a more compact staff.
