Learn any song by
ear, in tonic sol‑fa
and letters
Instrumentalist listens to a song and writes it back out in its simplest form: tonic sol‑fa and letter notes. A Swiss Army knife for anyone who plays by ear.

Frequently asked questions
Everything you need to know about transcribing music with Instrumentalist.
What do I get for free?
Five songs a month, on trumpet or piano, on a free account, no card. On Windows and macOS that is five full songs a month, up to three minutes each, read on screen. On Android and iPhone it is the first minute of five songs a month, started from a YouTube link. A subscription adds the other three instruments, longer tracks, the whole chart and every export.
Why do I need an account?
Everyone has a free account, free and paid alike. It is what ties your five free songs a month to you, so they cannot be reset by reinstalling, and it keeps your library and your devices in sync across the app and the desktop build. We use your email for your account and your receipts. Marketing email is a separate choice you opt into, never a condition of using Instrumentalist.
Which instruments can it read?
Trumpet, saxophone, bass, piano and guitar. AI separation lifts each one out of a full mix so it can be transcribed on its own.
Does it work offline?
The desktop app does. It transcribes on your own computer and only checks in about once a week to confirm your subscription, so it is fine on a plane or in a hall with no signal. The mobile app transcribes in the cloud, so it needs a connection to analyse a new song. A song you have already opened from a file on your phone can still be played back from that file.
How many devices can I use?
Player and Studio each run on up to two devices, any mix of phones, tablets and computers, so your own phone and laptop are both covered. Ensemble is the team plan, with 3 device seats for your group and the option to buy extra units for 3 more seats each, for a band, school or worship team. You can see your devices and remove one to free a seat at Manage your devices.
What can I export?
Letter notes and sol-fa as text and CSV, plus MIDI, on every plan. Studio and Ensemble add printable PDF charts. Ensemble also exports engraved sheet music as PDF and MusicXML.
Can I cancel?
Any time, from the billing link in your receipt or “Manage subscription” in the app. Your access runs to the end of the period you have paid for. See our refunds policy.
Is it priced in naira?
Yes, and at a discount. Prices show in US dollars and switch to naira automatically at checkout for visitors in Nigeria, converted at a flat ₦1,000 to the dollar rather than the market rate. With the naira around ₦1,375 to the dollar, that works out at roughly 27 percent off. The exact saving moves with the exchange rate; the ₦1,000 rule does not.
Where can I learn everything the app does?
The user guide walks through every screen and control, from importing a song to exporting sheet music.
