Last night, I challenged myself to have a double duo identity. I separately recorded the bass and treble parts of Mozart’s Sonata No. 1, K. 318, scored for 4-hands at one piano.

Logistics-wise, I had to decide which part to render first as the playback for the other’s insertion. But that wasn’t fair to either pair of hands, since they sometimes interacted on equal footing??? or doubled their voices. 

Quickly, it became clear that Primo had more of a solo role and needed a firm underpinning in Secondo to breathe phrases through harmonic shifts.

So once a decision was made, Camcorder captured Secondo on playback while Primo listened attentively and spun a beautiful melody above it.
