It took me some time to figure out the perfect workflow, so I want to share these 4 easy steps to help you transform a guitar recording into a clean, readable score. Here is how to go from your fretboard to MuseScore.
Step #0: Set up your recording environment
- Guitar Input: Plug your instrument cable into the front input. Crucial: Make sure the INST (Instrument) button is engaged to match the signal level.
- Computer Connection: Connect the Scarlett to your Mac via USB. This powers the interface and sends the audio directly to your software.
- Amp Output (Optional): If you want to hear your real sound while recording, connect the Line Outputs (on the back) to your amplifier’s input. Be sure to keep the output volume low to avoid clipping the amp's input.
Since I'm on a Mac, I use GarageBand. It’s free, powerful, and already installed.
Launch GarageBand and create a New Empty Project.
The Golden Rule: Go to GarageBand > Settings > Audio/MIDI and ensure your Scarlett is selected for both Input and Output.
The Secret Sauce: Turn on the metronome and play strictly to the beat. This is what makes the final score readable instead of a rhythmic mess!
Hit record, play your part, and save your project.
Step #2: Clean Up and Export to MP3
Before converting, you need to isolate your best take.
In GarageBand, trim the silence at the beginning and end of your recording.
Go to Share > Export Song to Disk.
Select the MP3 (or WAV) format and name your file.
Step #3: The MIDI Magic with Basic Pitch
MuseScore cannot "read" an MP3 file to create notes; it needs MIDI data.
The most efficient way to bridge this gap is using Basic Pitch, a brilliant (and free) web app developed by Spotify:
Drag and drop your MP3 file onto the page.
The AI will analyse your playing and convert the audio into digital notes.
Click the DOWNLOAD MIDI button to get your
.midfile.
Step #4: Transcribe to a Score (MuseScore)
This is where the magic happens!
Open MuseScore.
Go to File > Open and select your downloaded MIDI file.
That’s it! Your sheet music appears instantly.
Pro Tip: Auto-conversion is rarely 100% perfect. Spend a few minutes in MuseScore adjusting note durations or moving notes to the correct strings on the tablature. It’s still infinitely faster than writing it all out by hand!
