Turn your guitar riff into a tab before you forget it

The short answer

Record the riff on your phone, drop the file into BeatMap, and read back the frets, the tempo and the key. Your recording never leaves your device. Your own clean take is the best case for this kind of tool, much better than a finished band mix.

What you'll get back

Here's a riff run through BeatMap, as it came out. The tempo and key are at the top, which is useful when you come back to an idea months later.

Our 4-bar demo riff, unedited. It got 27 of the 29 notes exactly right. One of the misses was a note from the chord in bar 4, which is the kind of thing to check on yours.

How to record it so it comes out clean

  • Get close. Hold the phone a foot or so from the guitar, in a quiet room.
  • Play it plain, once or twice. Save the slides and bends for the real take. They're not written in the tab anyway.
  • Stay clean. Use an unplugged or clean electric tone just for this. Distortion and heavy reverb make notes harder to hear.
  • Don't count in out loud. Talking and tapping can turn into extra notes.
  • One guitar at a time. Record the riff and the rhythm part as separate clips, and make a tab for each.
  • Set your tuning first. Standard, Drop D and half-step down are supported.

What it doesn't do

  • It doesn't write bends, slides, hammer-ons or palm mutes.
  • It has no editor, so a wrong note stays wrong in BeatMap. Pro and Master export MIDI, which you can fix in Guitar Pro or your recording software.
  • It doesn't write chord names or lyrics.
  • It may choose a different fret position from yours, because the same note lives in several places on the neck.

If you need to write riffs by hand as you go, a manual tab editor such as Guitar Tab Maker may fit better. If you want in-app editing and Guitar Pro files from a recording, compare Klangio.

A simple way to keep your ideas

  1. Name the recording before you forget what it was.
  2. Make the tab, and rename it if you need to.
  3. On Pro or Master, your tabs stay saved for good. On Starter, they stay for 30 days, so download the PDF of anything you want to keep.

Questions

Is my unreleased song safe?

Your audio stays on your device, because the AI runs in your browser. It's never uploaded. Only the finished tab (the notes) is saved to your account, and you can delete it. If you share a link, it shows the title, tempo, key and first 2 bars.

Will it work with an electric guitar through an amp?

A clean tone is the safest. We haven't tested heavy distortion, which smears notes together for any transcription tool. If you can, record a clean take of the riff just for the tab.

Can I record straight into BeatMap?

Today you record first, then drop the file in: use your phone's voice memo app, then an M4A, MP3 or WAV. On an iPhone, you may need to save the memo to Files first.

Does it handle Drop D?

Yes. BeatMap writes in standard, Drop D or half-step-down tuning. Change it in Settings before you make the tab. Other open tunings aren't supported yet.
