I've just been told I have to conduct the string orchestra at a music camp for one of my schools in July. The conducting part is fine, and the repertoire has been chosen (not by me), but I was wondering if you could suggest warm ups or exercises that your ensemble uses to kick off rehearsal.
The late Christopher Bunting wrote some very good string exercises for ensemble warm-ups, under the name "Pro Corda". He kept saying he ought to get them published, but I suspect he never did. The only Web reference to them that I can find is a copy of the composer's manuscript score in the Australia Music Centre, Sidney.
I particularly admired two of the exercises: one was full of hairpins with contradictory bowings (i.e every crescendo down, every diminuendo up); the other had rhythms that were different, but confusingly alike, such as three successive bars of triplet crotchet/quaver, dotted crotchet/semiquaver, semiquaver/two semiquaver rests/semiquaver. Christopher would continue conducting the ensemble at a tempo that I, for one, found too rapid for comfort, meanwhile keeping up a running commentary on our failure to make the distinctions.
As to the musical content: one was excellent pastiche Puccini, another second Viennese school.
I recommend them to any publishers with a large string catalogue.
