Nowhere else in Europe, other than London and Paris, will you find so many musical and theatrical performances. The good news is the low cost of seats -- so count on indulging yourself and going to several concerts. You'll get good tickets if you're willing to pay anywhere from 10€ to 45€. Pick up a Monatsprogramm for information and schedules.
For events that sell out and popular events for which the number of available tickets is reduced by season tickets and long-term subscriptions (such as the opera's summer festival performances), you'll have to go to the box office -- organizers of these events tend not to cooperate with outside ticket agencies. But for virtually everything else in Munich, you'd be well advised to head for München Tickets (tel. 089/54-81-81-81), where you can purchase tickets to cultural, entertainment, or sporting events.
