How often do the orchestra musicians get together to rehearse?
It depends on the orchestra. Most professional orchestras meet twice a day for two to three days before a concert. For example, rehearsals will start on Thursday morning and continue until the Saturday when the concert takes place. Most non-professional groups meet weekly and produce between three and five concerts a year. Your Chamber Orchestra usually meets every second week and rehearses for 2 and a half hours. In all orchestras, members must practice at home before the first and then between each rehearsal. Individual home preparation is probably the most important aspect of being part of an orchestra.
