Transposing...yes it is the one and only thing that is easy to do on guitar...lol

On the other hand, I think sight reading is a bit less difficult on piano than guitar.

Yes, I have a piano but I have little idea how to play it. None the less it has been very useful in learning music theory. I did learn how to play happy birthday but it may be a while before I get a handle on Golliwogs Cakewalk...lol

Truth is, nothing is difficult after one has diligently studied and consistently played every day, seven days a week, and reached the 10,000 hour mark...lol
