The Grand Piano – Musical Instrument
The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700, in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings.
In grand pianos the frame and strings are horizontal, with the strings extending away from the keyboard. The action lies beneath the strings, and uses gravity as its means of return to a state of rest.
All else being equal, longer pianos with longer strings have larger, richer sound and lower inharmonicity of the strings.
The inharmonicity of piano strings requires that octaves be stretched, or tuned to a lower octave’s corresponding sharp overtone rather than to a theoretically correct octave. If octaves are not stretched, single octaves sound in tune, but double—and notably triple—octaves are unacceptably narrow. Stretching a small piano’s octaves to match its inherent inharmonicity level creates an imbalance among all the instrument’s intervallic relationships. In a concert grand, however, the octave “stretch” retains harmonic balance, even when aligning treble notes to a harmonic produced from three octaves below. This lets close and widespread octaves sound pure, and produces virtually beatless perfect fifths. This gives the concert grand a brilliant, singing and sustaining tone quality—one of the principal reasons that full-size grands are used in the concert hall. Smaller grands satisfy the space and cost needs of domestic use; as well, they are used in some small teaching studios and smaller performance venues.
