easiest instrument to learn for adults
No instrument is particularly easy to learn. First, you must understand how to read sheet music, which is a feat within itself. If I was to pick an easy to learn instrument though, I would have to pick the violin. Once you learn fingerings and how to play in tune, the violin is probably the easiest instrument to learn as an adult. Another, I would say, would be piano. Yes, you would have to coordinate both your left an right hand and the same time, but you will learn chord structures and songs that can entertain your family for a lifetime.
