A hands-on ancient Greek music-theory and lyre-tuning studio for classics students, early-music performers, composers, and mythology-informed songwriters who must build authentic tetrachords, lock the three genera (diatonic, chromatic, enharmonic), assemble modal harmoniai inside the Greater and Lesser Perfect Systems, and hear period interval colors on a virtual lyre—not a passive myth encyclopedia, not a modern DAW, and not a poetry-meter tool. The core loop is pick a genus and named mode → place movable bridges on a multi-string lyre → validate interval ratios against seeded canonical recipes → audition plucks through on-device synthesis → run recognition drills → open repertoire cue cards that retune the instrument for hymn or chorus practice.

LyreGenus Mode Studio on iPhone and iPad.
Build tetrachords on an interactive 7- or 8-string lyre by dragging movable bridges, then lock diatonic, chromatic, or enharmonic genus using seeded just-ratio recipes with cents readouts on every string gap.
Assemble full harmoniai (Dorian, Phrygian, Lydian, Mixolydian, Hypodorian, Hypophrygian, Hypolydian and documented variants) from conjunct or disjunct tetrachords on Greater/Lesser Perfect System maps with mese and proslambanomenos anchors.
Audition any single string, tetrachord, or full mode through AVAudioEngine pluck synthesis with tension/brightness controls and a steady practice pulse—no microphone and no network required.
Run mode and genus recognition drills: the lab plays short seeded phrases; the user identifies genus, mode name, or interval quality; results show a session score breakdown and unlock harder phrase banks.
Open a seeded repertoire library of cue cards (Homeric hymn fragments, tragic chorus cues, Delphic-hymn sketches) each pre-tagged with suggested genus/mode; one tap retunes the lyre and highlights the working tetrachords.
Compare any ancient mode side-by-side with the nearest modern major/minor or church mode on a dual interval ladder, with Charts-based cents deltas and color-coded “shared vs alien” steps.
