Frequently Asked Questions


What is the relationship between TwinNote and Twinline?

TwinNote was inspired and influenced by three versions of Twinline music notation by Leo de Vries, Thomas Reed, and Doug Keislar (which have much in common with Bilinear Notation by José A. Sotorrío). These notations all share the same basic staff with two lines per octave, spaced a major third apart, and they all use more than one type of notehead to allow for a more vertically compact chromatic staff. See the Influences page for illustrations and more detailed discussion. The Music Notation Project also documents the differences between TwinNote, the various versions of Twinline, and Bilinear notation on this webpage.


Why the name “TwinNote”?

The name “TwinNote” refers to the two types of notes found in TwinNote (triangles pointing up or down). These two types of note represent the two interwoven whole tone scales, two “twin” series of notes in a “6-6” pitch pattern. This makes the pitches of notes more readily apparent and gives intervals a clear and consistent appearance.

TwinNote’s name also reflects its debt to Twinline music notation. While the name “Twinline” draws attention to the two lines of the staff (an incidental feature of the notation), “TwinNote” emphasizes its two types of noteheads, which is a core feature.
