The Rāga Orrery

Where melody becomes orbit.

Hear a melodic phrase travel inside a repeating rhythm. Follow each pulse, listen for the phrase, and watch the cycle return to its beginning.

Eight rāga study models · five rhythmic cycles · your own pace

How it works · three steps

01 · ChooseSelect a rāga study and a rhythm. These choices update the instrument immediately.

02 · ListenChoose Create orbit & play. Gold follows the rhythm; blue follows the melodic phrase.

03 · ReturnSam is the beginning of the rhythmic cycle. The melodic phrase has its own length; its return need not coincide with sam.

This is a bounded listening instrument. A rāga is a tradition of characteristic melodic movement, not simply a scale. The orbit is a visual analogy, not an astronomical explanation.

THE LISTENING FIELD

Build a rhythmic orbit

TIHĀĪ · THREE REPETITIONS, ONE LANDING

Repeat a short rhythm three times. Change its start, length or gaps to hear where the final stroke lands. Sam is pulse 1 of the selected cycle.

Three repetitions. Hear the journey, or choose Reveal return to read the final landing.

When do two rhythms meet?

periodicity · relative phase · return

Give both rhythms the same steady pulse. How long until both cycle beginnings return together?

Choose two rhythms, then find their next shared beginning.
Watch the cycles & see the calculation
Boundary: the rings are a mathematical periodicity instrument. The central phase witness is abstract—not the Moon, not a planet, and not a claim of astronomical causation. It shows relative phase and the return of two cycle-start markers.
Method / analogy boundary

Orbit is a visual and structural analogy for cycle, relative position, recurrence, and alignment. The Rāga Orrery makes no claim that astronomical bodies cause or determine rāga or tāla.

MIDI is an export, not the tradition. The file can preserve tempo, tonic, selected identifiers, markers, synthetic rhythm events, note events, and phrase-mode metadata. R1.1 can approximate selected stored pitch trajectories through MIDI pitch bend, but it still does not preserve semantic gesture meaning, complete meend, traditional intonation, vocal nuance, tabla technique, timbral detail, provenance richness, or improvisational knowledge.
