Many musicians such as flute players, violinists, violists, cellists, trumpet players, trombone players, and tuba players can carry their instruments to and from rehearsals and performances. Pianists unfortunately cannot carry their instruments around with them as they are not portable like the instruments I mentioned above. The pianist usually ends up playing an unfamiliar piano in an unfamiliar acoustic space, be it a concert hall, or some other space such as a school theatre or senior’s residence. This presents a huge challenge because the pianist has to change the way they play to figure out how to coax the best sound out of an unfamiliar instrument, and also adjust to the acoustics of the performance space (which may be a completely dry acoustic or a very wet and echoey space). The piano itself may also be in pristine condition, be almost unplayable, or sound bad.

Virtuoso pianist Anton Kuerti (1938 – ), who is well known in Canada, demonstrates in a short 6 minute video some of the things that can be done to fix tonal defects and regulate the piano action to make it easier to play before a performance. This is not recommended as something the average pianist should do, as it takes special knowledge about pianos, and most theatres and concert halls would not allow a pianist to mess with a piano unless they were a qualified piano technician.
