Jam Maestro is an iOS guitar-tab based music sequencer, designed from the ground up to take full advantage of a touch screen interface. Write tab using up to 16 guitar, bass or drum instruments. Play it back and hear how it sounds using 1000s of high quality real samples.

Designed for composition

Jam Maestro is not a tool to help you learn guitar. It's your composition assistant you can take anywhere and gives you the power to sketch out ideas quicker than you thought possible.

Music Theory

Music theory has been built into the heart of Jam Maestro.


Unique playing interface to help you compose. Highlights notes outside of your current key that will still sound good with your current key.


Notes that harmonise well together are highlighted.

Jam Mode

Let Jam Maestro be your backing band.


Set your instruments to loop between certain bars, and start recording in Jam Mode. Play along to your backing instruments and as you play your notes will be transcribed to tab on the fly (including the backing instruments). Once your jam is over copy and paste your best ideas into your main composition.

Key Analysis

Analyse the notes in your composition to understand the keys it could potentially be in or transition to.


Program in key changes at points in your tab so that the playing interface stays in sync, allowing you to jam along to your composition seamlessly.

Intuitive interface

Jam Maestro was designed to be more than just a toy... we designed the app we wanted to use

Guitar Tab

Compose, sequence and playback songs in guitar tab format, meaning any compositions can be easily translated to and played in real life.


Full touch screen fretboard means you can quickly and intuitively enter your tab rather than struggle with a standard numpad


Intelligent interface and gestures means you can edit your tab faster than any other app


Load up to 16x Guitar / Bass / Drums. Use Midi and Inter-App Audio ‘instruments’ to invoke and sequence background apps/hardware.


Easily program tempo, volume, stereo panning and key changes to occur at the right part of your song


Perform your notes directly into the app and record mode will transcribe them as you do

How to write a metal song in 5 minutes using Jam Maestro

App Reviews

Don’t take our word for it, take theirs.

This app gives me the power to pro-produce music even places that I can't physically play guitar. I've used this as my main song-writing tool for years now. Well worth the price!

This is my go to for writing down and figuring out songs for my band to play. Jam Maestro has everything I need. I can write for guitars, bass, and drums, all the sounds sound realistic, and I can even export and email my songs to my band mates directly from the app.


App Store

The level of performance this app allows you to achieve by just tapping the tab in on your phone is amazing! From drums to bass & guitar you can write every part of a song within this app and then hear how it sounds together. It even has effects and automation. I love it!

There is nothing like this out there. The best tab > music app. Experimenting is easy. Thank you for this app I searched for ages to find similar and could not.

I've used this app for years. Jam Maestro has become a crucial tool for composition and collaboration for me.


App Store

I'm not exclusively using this app for the guitars but I've found so many sounds that this app will accomplish that are not in other guitar apps. The chug feature is awesome and I really am working on creating guitar tracks that sound like a real guitarist playing my music. The only guitars I've found so far that have the same high quality are loops playing somewhat generic patterns, I can't and won't use them for anything other than figuring out chord progressions.
