41edo Keyboards: Difference between revisions

This page discusses extending the concept of the [[The Kite Guitar|Kite Guitar]] to a keyboard or tapping instrument.

The usual guitar vs. keyboard trade-off is that the keyboard has more range and polyphony and freedom of voicing, but the guitar is more expressive (bends, slides, vibrato etc.) Tapping instruments are included here as these have much the same trade-offs. This page discusses the design of an instrument that does what a 61-note 12-edo keyboard does. Instantly play in any key (or at least every other key) without using transpose buttons, and a 5 octave range, so 4 octaves low-tonic-to-high-tonic range is guaranteed in every key.

There are various DIY options. Or these existing high-end instruments could be retuned to 41-edo:

=== Full-41 layout===

The obvious full-41 layout has keys one edostep apart adjacent to each other, forming a column. The top of one column "jumps" to the bottom of the next column. It's like the [https://hpi.zentral.zone/tonalplexus Tonal Plexus] layout, but omitting 80% of the keys to reduce 205-edo to 41-edo. This picture shows 2 octaves, with the white keys running C to C. ~~Each white key has a sharp (upper right) and a flat (lower left).~~

The columns with white keys have 3 notes, and the columns with black keys have 4 notes. Most white keys have a black-key sharp to its upper right and a black-key flat to its lower left. This picture shows 2 octaves, with the white keys running C to C.

 This page discusses extending the concept of the [[The Kite Guitar|Kite Guitar]] to a keyboard or tapping instrument.
-The usual guitar vs. keyboard trade-off is that the keyboard has more range and polyphony and freedom of voicing, but the guitar is more expressive (bends, slides, vibrato etc.) Tapping instruments are included here as these have much the same trade-offs. This page discusses the design of an instrument that does what a 61-note 12-edo keyboard does. Instantly play in any key (or at least every other key) without using transpose buttons, and a 5 octave range, so 4 octaves low-tonic-to-high-tonic range is guaranteed in every key.
