Apart from fiddle tune books (see tip #3), another great source of music for class is quadrilles. There are just hundreds of them out there for free on the net, and they’re all in eight bar phrases, so you can use them straight off the shelf. In fact, it’s probably the tradition of quadrilles that shaped a lot of ballet class musical culture in the first place. Those endless glissé exercises in fastish 6/8s? Straight from the quadrille. Many variations in ballets are fashioned on quadrille rhythms, and ragtime evolved from quadrille, which explains why both rags and quadrilles work for class.
Each quadrille usually contains five different dances, all in a similar tempo range. Conventionally, they alternate between 2/4 and 6/8, with a galoppy thing at the end, so you can joint a quadrille like a musical chicken and use it for barre, turns and petit allegro. Less commonly, there are also ‘waltz quadrilles’ and ‘mazurka quadrilles’, and quadrilles based on operas or popular classics of the day. If you thought ‘hooked on classics’ was so 1970s, think again, quadrille writers were merciless when it came to carving up other people’s music to dance to.
