Is it unusual to compose music as a hobby?
In short, the answer is no. It is not that unusual. Music is popular, attracting many people. For serious music fans, composition and music listening are somewhat interconnected.
Not everyone is a professional, and composers aren’t the names you hear on the radio, but they’re the ones crafting the sound. It’s a popular hobby and a remarkably satisfying skill!
People listen to music and sometimes play music as well; that may be called composing pieces (even if they are short and simple). Music composition is quite a popular hobby when you break it down.
