# Comment on a version
Source: https://docs.aden.space/docs/help/work-together/comments/comment-on-a-version

Pin a note to a moment or a section of a song, mention people, and attach voice memos or files.
## Leave a comment [#leave-a-comment]

1. Open a track, go to the versions and pick the version you want to review.
2. Choose where the note goes:
   * Click the waveform to pin it to one moment.
   * Hold ⌘ (Ctrl on Windows) and drag across the waveform to mark a section.
   * Or use the clock buttons in the composer to stamp where the song is playing.
   * Leave the time empty for a general note.
3. Write your comment. Type @ and a name to notify someone.
4. Press Enter to post. Shift and Enter starts a new line.

Your face marks the spot on the waveform. Drag it to move the comment to another moment.

## Add a voice memo or file [#add-a-voice-memo-or-file]

Record a voice memo or attach a file to your comment. Hover a voice memo and press the captions button to write out what was said. A MIDI file plays right in the thread.

  Files in comments need Ultra or up. On a share link, the better of your plan and the sharing team's plan applies.

## Drum ideas [#drum-ideas]

Write about a drum ("the kick is way too boomy", "change the clap") and three new sounds appear under your comment, under **Kick ideas** or the drum you named. Click one to hear it, download it as a WAV, or open it in the tools to keep shaping it. It works for kicks, snares, claps, hats, crashes and rumbles.

## Comment without an account [#comment-without-an-account]

On a share link with comments on, anyone can comment. Aden asks for a display name the first time. Add an email, and if you later sign up with it, your comments move to your account.
