What musical Instrument did Sherlock Holmes like to play?

There is no mention in the original Sherlock Holmes stories by Sir Arthur Conan Doyle that Sherlock Holmes played any musical instrument.

However, there are a few instances in popular culture where Holmes is depicted playing the violin. This is likely due to the iconic image of Holmes playing the violin in the popular BBC series "Sherlock" with Benedict Cumberbatch.

While this is a great interpretation of the character, it is not based on the original stories.
