How long does it take to learn an instrument?

This is a difficult question to answer. It would be truthful to say that you never stop learning no matter how long you play. But the length of time that it takes before you can play recognisable tunes and melodies and think about joining groups, bands and orchestras is a different matter. This really comes down to two main factors such as which instrument you are learning and how much practice you do. Some instruments take a little longer than others to get the hang of, such as the violin or trumpet. While others, like the keyboard or guitar make a good sound immediately but need to be controlled.

The real secret of success though, is being able to practise regularly and constructively on an instrument that you enjoy playing.
