"It's a game changer...

…I’ve just got hold of Quartet 1 – an utterly unbelievable playalong practice tool that’s available for iPad”
Nigel Price, UK Jazz Guitarist

Nick Smart, Head of Jazz, Royal Academy of Music, London

"Looking forward to using this myself...

…this is a really great resource for practice (with) some of London’s finest jazz musicians.”
Mark Armstrong, Jazz Professor, Royal College of Music, London

A repertoire of over 100 of the most popular jazz standards recorded ‘live’ in a London recording studio just for you. With animated chord charts that follow every beat, and full screen animated chord diagrams if you want them.

Now imagine being able to select one of 8 mixes for each jazz standard that best suits your instrument…in real-time. With the facility to change key with just one touch. Speed up or slow down the audio with no loss of quality.

Imagine all of this (and more) in one feature-packed app for iOS.

For jazz instrumentalists and jazz vocalists of all levels, Quartet is the app you’ve been asking for… and it’s available right now for about the same price as the cost of 2 small lattes!
