Musicians give several reasons for performing virtual concerts in Second Life: 1. To make money, though payments are much smaller than in real life concerts. Some musicians earn $5000 Linden dollars (about $20 USD) for a one hour concert. 2. To use downtime and rehearsal time productively and earn supplemental income. Virtual concerts allow testing new material. 3. To develop new material and prepare for real life performances by having a live audience provide feedback. Students at a Swiss conservatory use virtual concerts before exams.
