The starting melody

Start with a motif and hear its answer

The first bar introduces an idea; the second responds to it. The starting C minor phrase rises from C through E-flat to G, leaves a gap, then answers by stepping back to C. Press Play once to hear the complete two-bar result before changing anything.

Choose a major or natural-minor key and an arch, rising or falling contour. Density offers a spacious, balanced or every-beat starting rhythm. Variations use phrase shapes and gaps, giving you material to develop rather than a judgment about the one correct melody.

Give every beat a pitch, rest and length

Select one of four beat slots in either bar. Change its pitch across C3 to B6, make it a rest, move its start within the beat or change its duration. Chromatic notes are available when the musical idea needs them; editing is not limited to a fixed scale palette.

The editor keeps each note inside its beat. A later start can shorten its visible held length so the result stays monophonic. Lock a slot to preserve its exact settings through new variations or key changes. Locked notes may fall outside a changed key; Undo lets you return to a previous phrase.

Keep a sketch you can develop further

MIDI preserves the displayed pitches, rests, starts and durations over eight quarter-note beats. Choose your own lead, keys or other instrument after importing it. The reference WAV contains a simple synthesized tone following the same musical events.

A settings link restores the editable phrase without autoplay. This browser tool makes a short musical sketch without signup, recording or AI credits. To develop it into a track, keep the file and bring it into your chosen session; opening TunePal’s app does not transfer it automatically.
