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
