Endless Piano — Calm Melody Generator Online

No. The melodies are composed in real time by your browser: pre-written musical phrases (over 60 across the four moods) are varied, transposed and harmonized on the fly. The piano notes themselves are recordings of a real grand piano.

There is no fixed loop. The phrase order, octaves, dynamics, chord choices and accompaniment patterns are re-randomized continuously, so the stream keeps changing for as long as it plays.

Because it is a real piano: the engine plays 21 sampled notes of the Salamander Grand Piano (recorded by Alexander Holm, CC BY 3.0), with velocity-dependent brightness, stereo placement by pitch and convolution reverb. While the samples load, a synthesizer modeled on piano acoustics fills in, so playback starts instantly.

Yes. It runs in any modern browser, and the scheduler plans music far enough ahead that playback continues when the tab is in the background. Audio starts after you tap Play.

Yes. The calm and dreamy moods are made for background listening during work, study or meditation. For sleep, set the auto-stop timer — the music fades out smoothly over the last 20 seconds instead of cutting off.

No neural network is involved. The music comes from algorithmic composition: a curated phrase library, music theory rules (diatonic chords chosen to fit each bar of melody) and a seeded random generator for variation.
