After my great grandmother died a couple of years ago now, my mom and I aquired her piano, Which she (my Great G ma) bought sometime in the 60's. Its a Wurlitzer, Its a wall piano (I think thats the correct name for it, It only about 1ft and a half deep). I think its made of Rosewood, as it resembles my Ibanez fretboard much. it came with a bench with built in storage spce for music, Which I think is also made of Rosewood. I cant really play piano, but I want to and well, from what I can hear, its about one step out of tune. I did a google search and have some some good websites, but just wanted you're input's. I also have some other questions... What is the lowest and highest note on a Piano In tune? How much do you think a 40 year old Werlitzer wall piano is worth(not that were going to sell, just for reference)? Is paying $200 plus dollars to get it professionally tuned, worth it? Thanks.
