A keyboard duet can be anything from two kids picking out "Chopsticks" on an old upright piano to the cathedral-filling two-organ concerti of Antonio Soler.
We'll have a selection of music for four hands this week - some of it meant for the concert hall, some for the parlor; some of it virtuosic recital material, some mostly for fun.
And we'll leave the "Chopsticks" behind, thank you very much.
