The modern piano developed its form from two keyboard instruments, the clavichord and the harpsichord, which originated from early in music history. These keyboard instruments operate on the principle of direct connection between the applied force or pressure of the player on the keys, and the volume of sound. Meaning, the harder the pressure or force the player applies on the keys, the louder the sound of the instrument, the lighter the touch, the softer the sound. Earlier musicians, however, encountered a problem with the clavichord and harpsichord: the sound was relatively diminutive as compared to how they would have wanted it to be, considering the fact that keyboard instruments were often played in large rooms (chambers), cathedrals and churches.

Around the year 1700, Italian instrument maker Bartolomeo Cristofori (1655-1731) created the new keyboard instrument and coined its name from the fact that it could both play "piano" (soft) and "forte" (loud), addressing the problem of the old keyboard instruments. Thus, the pianoforte, or what we call shortly now as the piano. Aside from the direct connection between the fingers on the keys and the sound, the piano also has two different pedals which are the “sustain” or damper pedal and the “soft” pedal. The sustain pedal allows the pianist to hold the tone or sound even after releasing the key. The soft pedal veils or muffles the sound. There is also a third pedal called the “sostenuto” pedal. However, not all pianos have this.
