Arrangement lessons from stems

Take a song apart instrument by instrument to understand its arrangement or rework your own.

Soloing a stem reveals decisions you cannot hear in a mix: a guitar that drops out before the chorus, a bass line that climbs into the bridge, harmonies that arrive only on the last hook.

Stems come out aligned from the same start point, so you can import them into any editor and rebuild the song around the parts you keep.

Arrangement lessons from stems

Writers learn by listening to how songs are put together. The stem splitter separates a track into as many as twelve parts, so you can hear what the piano does under the verse or where the backing vocals enter.

It is equally useful on your own demos: keep the drums and bass you like, and rewrite what sits above them.

What you can separate

Lead and backing vocals

Hear the main voice and the harmonies separately.

Rhythm section

Drums and bass come out on their own for study or replacement.

Keys, strings and more

Guitar, piano, keys, strings, brass, woodwinds and synth are split where present.

Instruments sharing a range can bleed into each other a little.
