Tripod Notation is an adaptation of staff notation to work with 225:224 tempered out ([[Marvel|7-limit Marvel Temperament]] and more specifically [[Magic|Magic Temperament]]. 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 ~~region~~ corresponding to three pitches of a triad.

Accidental symbols are taken from the Sagittal set. Typesetting and MIDI files are generated by LilyPond.

The three lines of the Tripod staff can be thought of as three strings. 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]].

A 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 black keys then correspond to staff positions and the white keys to accidentals. You need to add one more key for the 22 note MOS. For use on a retuned Halberstadt keyboard, the Tripod staff positions must alternate between F♯, G♯, and B♭ keys for the ideal Tripod adaptation and C, E, and G keys for alternate feet. This adds up to 18 notes per octave.
