You don’t need to be a trained musician to select music for your broadcast. In fact, professional musicians use terms like “sweet”, “hot”, “dark” and so on to describe a tune. You can too! These descriptive words describe a sensation or emotion, which is just what a piece of music will evoke.
If a tune is “too busy”, that means there is too much going on. It may evoke the sensation of chaos or confusion, there are possibly too many instruments playing or the melody jumps all over the place with no clear direction.
A tune that is described as “light” or “relaxing” will most likely have a melody or harmony that transitions smoothly. It moves seamlessly from one music thought to the next.
Use descriptive terms like the ones above to search for just the right tune. Experiment by searching on a few terms to see how the musicians have described each piece.
