I know strings can be hard sometimes, but it's easier then any woodwind or brass instrument. ex. my bassoon, one key can play up to two notes each. and on a string instrument all the notes are all laid out for you, you just have to put your finger in the right spot. One of my favorite sayings, "It's easy to play a musical instrument: all you have to do is touch the right key at the right time and the instrument will play itself."- J.S. Bach
