笙Time vs PentaMonochord

"笙Time" is a "笙(Sho)" simulator. "笙(Sho)" is traditional Japanese instrument for "雅楽(Gagaku - Japanese traditional music)" It has thin 17 bamboo pipes. It sounds like small pipe organ. Each button play blow notes. ( ' means upper octave notes) "乞" : { A, E, A', B', E', F#' } "一" : { B, D, E, A', B', F#' } "工" : { C#, D, E, G#, A', B' } "凢" : { D, E, A', B', E', F#' } "乙" : { E, A', B', D', E', F#' } "下" : { F#, G#, A', B', D', F#' } "十" : { F#, G, A', B', D', E' } "美" : { G#, A', B', C', D', F#' } "行" : { A', B', D', E', F#' } "比" : { A', B', C', D', E', F#' } Each note is not on "Equal Temperament", but on "Pure Temperament" or "Pythagorean Temperament". Also the default base key A=430Hz Tilting your phone, the playing volume change. Push a button and drag your finger to out of the button, then the note can be hold. Setting view can set below parameters. - Available fingering mode "Sho" has limit fingerings. If you want to use all button, set this mode off. - Attack and Release Envelope You can set envelope time (0 to 1000 ms) - Tone Color You can select tone color (Hard/Medium/Soft)

The Pythagoreans’ foremost innovation was to correlate pitch relationships to calibrated speaking lengths of a string on a monochord. Now, for the first time, there’s an app for that! Use IntervalBlocks to build a two-octave G pentatonic scale on the PentaMonochord using only octaves and fifths. Touch any block to see and hear its interval again, and watch the Hertz box to see how the frequencies of the two notes relate inversely to the string lengths represented by the IntervalBlock. Touch the note labels any time to play a pentatonic tune. Press “Switch to Game” to join the Pythagorean pantheon by building the whole scale with the minimum number of steps. The Intro and the Background Information explain the monochord system in detail, and the Timeline puts it all in perspective.
