![]() ![]() You need to add one more key for the 22 note MOS. The black keys then correspond to staff positions and the white keys to accidentals. A stringed instrument tuned in thirds with semitoes down the fretboard will naturally work with Tripod Notation and look a lot like a Kite Guitar.Ī generalization of the Halberstadt keyboard for Tripod Notation can also be imagined: divide the octave into three regions each with a pattern of black and white keys that looks like F to B in the Halberstadt mapping. The three lines of the Tripod staff can be thought of as three strings. Typesetting and MIDI files are generated by LilyPond. As a major third doesn't divide into equal toes, this is in the general case a notation for a rank 3 temperament or 5-limit just intonation.Īccidental symbols are taken from the Sagittal set. ![]() In magic temperament, a toe divides into two equal semitoes and different accidentals become equivalent. Accidentals move pitches by 25:24 or 36:35, intervals called a "semitoe". With 225:224 tempered out, 16:15 and 15:14 are identical and called a "toe". Other staff positions are an approximate 16:15 from the adjacent line. Each line is separated by a major third approximating 5:4 and the line is the centre of a pitch region called a "foot". Tripod Notation was originally described in 2009 and involves a three line octave staff. The 9 note "tripod scale", taken from a rank 3 temperament, is used instead. Tripod Notation solves the problem that Magic Temperament doesn't have a proper MOS with or close to 7☒ notes. More generally, the umbrella of Tripod Notation covers the related ideas of Tricycle Notation and Tricolour keyboards that involve a division of the octave into three regions corresponding to three pitches of a triad. Tripod Notation is an adaptation of staff notation to work with 225:224 tempered out ( 7-limit Marvel Temperament and more specifically Magic Temperament. ![]()
