Tried it myself twice: in the Deutsche Museum, in the “musical instruments” section, you can play on any keyboard instruments from the 18-19th century – harpsichords and clavichords, and even on a splendid Steinway & Sons Grand Model D piano. But in the Munich City Museum’s same section, they don’t allow you to touch anything with your hands! Boo!
