An out of tune piano is discouraging to students of any age.
So, if you can't remember the last time the tuner came, it is time to call. For a point of reference. Before I got my hybrid piano, my tuner came 3 times a year.
See you in lessons soon.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
