"If you actually know your stuff, you will know that a good quality harmonica is gonna cost way more than a few dollars... especially a chromatic, which is $100 or more. Even though most harmonicas have good manufacturing, proper maintenance and preventative measures are still needed. Aside from the cost of repairs, you might have difficulty finding someone skilled enough to repair your harmonica, especially if you are not good at repairing!"
"For centuries, the notes in pieces of music have been described by writing them on staff lines.
Staff notation is based on staves. A stave is a set of five horizontal lines, where each line (and each space in between) represents a different note letter. Note symbols are placed either on or between the lines."
