1. Listen to audio and watch video of as many San Francisco classical groups as you can. The typical San Francisco string duo, string trio, and string quartet have multiple audio and video samples available on their Gigmasters press kits.

2. Thoroughly read previous client feedback. Many Gigmasters clients who have hired a classical group in San Francisco have left useful feedback about their experiences. Also keep in mind, a full classical ensemble in San Francisco might be larger than what you'd like, but often times a classical group can reduce the number of performers in order to suit your budget.

3. Book early. A professional San Francisco CA string ensemble sometimes needs to be booked 6 to 12 months in advance.

4. Get a contract and read it carefully. Most professional San Francisco chamber ensembles and string quartets will also require a deposit in order to secure them.

5. Follow up with your San Francisco California string ensemble as often as you need to. Don't be shy about making sure your classical group knows exactly what classical music selections you'd like played!
