I don’t normally write reviews. In fact, I hate writing reviews and taking surveys. But, Jonathan has created an app that revolutionizes practicing and helps you learn a song inside and out and musicians needs to know about it. The tracks are actual performances so it feels like you’re playing with a live band. The mixes are great, but you can tweak them if you want to focus on a particular instrument. The chords are correct and in common keys. Want to learn more about the song and what makes it pop? Hit the information button. Getting better at performing has never been easier. Thank you for the time and effort it must’ve taken to get the app just right!

In addition to beautifully recorded LIVE backup performances by the best pianists, bassists, and drummers in NYC (whose time is IMPECCABLE, pace Aebersold), you get chord charts for a very generous (and growing) selection of tunes. And you can vary the metronome settings and adjust the pitch levels without significant audio degradation to boot. There’s no competition: I used it for one tune on tryout and immediately signed up for a year. It’s the only app I have that I don’t regret having to subscribe to! Hats off to all involved.

No other play along comes anywhere close to the feel book. The feel book uses the top tier New York players and it literally feels like you’re on stage with them. On top of that, the tech features and sound quality are on another level. They also have a menu that includes song history that explains where the changes came from. I’m loving this app!!!

This is the best jazz play along app, bar none. The fact that all of these are real tracks played by Real musicians makes this an invaluable tool. In addition to being great to just practice with, the feel, Book can also help you to really work on skills like comping. I can’t recommend it enough.
