Overview

Are there times when you just feel like listening to some Keb' Mo' or Eric Clapton? Do you wish you could play along? Circuit Playground Express and CircuitPython may be all you need to add some tambourine or cowbell to the mix. And what is a vibraslap anyway?

The Blues Playground is two blues musical instruments in one. First, it's a collection of common percussion instruments played using a hand-held paddle that resembles the shape of a tambourine. You can play with the beat or add accents to spice up the song. The Blues Playground has a second mode that steps through a typical blues chord sequence one beat at a time. The Chords Mode can be used as the musical foundation of your own blues song -- just add lyrics. If you can tap to a beat, you can play the blues!
