iRealBook application for your smartphone helps your Jazz practicing
The reason why I like this application so much and recommending you get it as well is because you got pretty much every tune you’ll ever need to know in the Real Book and you can not only change the tempo, you can also change the key and the styles. This makes it a great practicing tool to develop your improvisational skills in all 12 keys and having fun while doing so.
I pretty much use this app on a regular basis, pretty much everyday to be quite honest since all I practice is Jazz. Download it today, you won’t regret it!
