Few themes in classical music are as well-known as the beginning of Peter Tchaikovsky's First Piano Concerto. The chords of the first bars span almost all 88 keys, covering a full seven and a half octaves. What is less well known is that there is a first version of the concerto, which was only rediscovered later. Thanks to Kirill Gerstein, it can be heard in concert halls again today. He himself had noticed a note in the second movement that simply seemed wrong to him. He did some research, came across other versions of the concerto and ended up writing an entire article about this note. But don't worry, you don't have to go into detail to get close to Tchaikovsky's music. Melodious, sonorous and with all its emotional shades, it appeals to audiences just as much as it did 150 years ago.
