This is completely incorrect. The guitar is one of the hardest instruments to master. Anyone can "play" guitar... but not everyone can perform on it well. If you're just interested in playing rock chords, then you don't need a teacher. But if you want to become a good musician, you better believe you're going to be reading music, studying with a teacher, and logging some serious hours into practicing.D.T. said:I play guitar and piano. Guitar is easier to learn but piano is easier to play...and if you get a keyboard, you don't have to tune it all the time like you do a guitar. You don't have to tune pianos as often, but you still have to tune them. Personally I like piano better.
Guitar is very easy to learn IMO...and you don't really need a teacher. It's easy to learn, but not to get good at. You have to practice endlessly and some things are very difficult to play, especially if you have small hands. You might want to take that into consideration. One advantage to guitar is that you don't have (though it's still a good idea) to know how to read music, you can read tabs, which are easy to learn. Piano is very difficult to learn.
Piano, on the other hand, is a much easier instrument. Sure, reading the bass clef can be difficult initially, but once you get that going, the rest flows naturally. I started playing Waltz for Debby (by ear) the other day, and was surprised at how easy it was. I found sheet music for the tune, and I won't be surprised if I get the piece running within a week. I have no background in piano.
