Sigma Squared Music

We are a publisher of high-quality sheet music featuring original compositions, unique arrangements, and detailed transcriptions for solo instruments, small ensembles, and band.

We believe that music should be as enjoyable to play as it is to listen to. That's why we focus on creating compositions and arrangements that are unique yet approachable, with every player's part engaging and relevant.
