NEW: Free practice app w/ stem separation, SHED →

Make the back-and-forth the easy part of finishing your music

One place to play drafts for cowriters, bandmates, and clients, and hear exactly what they mean

No credit card required.

A home for works in progress

Organized without the busywork

Projects, songs, versions, attachments, album art, and notes, all where they belong instead of scattered across chats, drives, and inboxes.

Version History
Every song keeps its versions in order, with notes about what changed. No more FINAL_final_v3.wav
Workspaces
A personal workspace for your own projects, and team workspaces for your band, production crew, or clients
Private by Default
Your work is only visible to the people you share it with: per project, song, or version

Feedback that lands

Listen together, decide faster

“Something's off around the second chorus” becomes a comment pinned at 2:41 on the version it's about, next to the conversation that resolves it.

Time-Synced Comments
Feedback pinned to exact timestamps, marked on the waveform, with threaded replies and voice memos
Stems & Mixer
Upload stems (or auto-split a track) and let anyone solo, mute, and balance parts right in the browser
Feedback to Done
Turn comments into todos, resolve them as you go, and tag new versions with what they address

Frequently asked questions

What is Concerto?
Concerto is a web app for collaborating on music that's still in progress. You upload songs, share them with collaborators or clients, and collect feedback tied to exact timestamps instead of chasing notes through texts, emails, and voice memos.
Is Concerto free?
Yes. The Solo plan is free and includes up to 50 uploads, with unlimited collaborators, time-synced comments, and version history. Ensemble ($8/month or $80/year, per workspace) adds 10× the storage, stem uploads with an in-browser mixer, automatic stem separation, and version comparison.
Do my collaborators need to pay?
No. People you share with just need a free account. They can listen in full quality, comment at timestamps, and even play with the stem mixer on songs that have stems.
Does Concerto replace my DAW?
No. Concerto covers the space between exports: sharing drafts, collecting feedback, and keeping track of versions. You keep making music in whatever tools you already use.
Can Concerto split a song into stems?
Yes. On an Ensemble workspace you can auto-split any uploaded track into vocals, drums, bass, and the rest, or upload stems you bounced yourself. Anyone you share with can mix them in the browser.
