You can tune a hard piano in just a few simple steps: First, get your hands on a hardwood piano and tune it to a particular tuning.
Then, play a melody from the piano’s key signature (called a “scales”) and tune the piano to that key.
(A piano key signature is a series of notes, arranged in a certain order, with one key at the top and the other at the bottom.)
Next, play the melody from each of the six scales on the piano.
The notes from each scale are called keys.
The six keys are called major scales.
For example, C major is the key for C major scales and B minor is the keys for B minor scales.
The major scales are also called major key signatures, or the “major key signatures” (MKT), and they are played on the key of C. Each key signature has its own number and its own pitch.
For instance, F minor keys (which are called F# minor keys) have a pitch of F, while F major keys have a pitched pitch of D. Finally, you can learn how to play the minor keys by practicing these notes and using the keyboard.
