The Relevant Research To Piano Tuning Theory And Practice

The keyboard instruments have prevailed years in Europe. From the Clavichord of 15 centuries to batch of 16 centuries, till the modern piano of 18 centuries, the keyboard instruments have experienced development of centuries before the real modern piano came into being.
