Piano Tooners 1932 film complet
Tom and Jerry (the human versions, not the cat and mouse) work as piano tuners. After seeing them at work and several creative ways of tuning a piano (such as removing the offending key and cutting the key itself to a shorter length), the two attend an opera singers performance. The singer passes out when the piano plays a wrong note, and Tom and Jerry are pressed into service to re-tune the piano. After pulling the offending key from the keyboard like a bad tooth, the two give the opera audience a jazz piano performance, with the now recovered opera singer joining in.
