Piano Tuning is the very back bone of all piano services offered by your local piano technician. Fluctuating humidity as well as normal, continual decrease of static tension causes all pianos to go out of tune. Depending on where the piano is located, the amount of humidity change from season to season, the quality and condition of the piano and how much the piano is played, tuning may be required 2-3 times per year. A piano being in tune (with an equal temperament set) and at standard concert pitch of A440, is a necessity for any pianist, from the beginner to the expert. For a beginner, learning to recognize certain tones and their relation to other tones from one piano to the next is essential. If a child’s piano at home sounds different than their teacher’s piano, they may become easily confused and discouraged. For the expert pianist, proper equal tempered tuning facilitates the use of adequate phrasing in a piece of music, easier recognition of which melodies should be accented within the music and faster memorization.
