Grand Piano

Looking to buy a grand piano, but don't know what to buy? At Carlingford Music Centre our experienced Piano Specialists can guide you through our range of grand pianos. We only employ Australia's leading piano tuners giving our pianos a tone and playability that is unique.

A grand piano utilises a horizontal frame & strings, 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.

There are many sizes of a grand piano. A rough generalization distinguishes the concert grand piano (between 2.2 and 3 meters [7 ft 3 in–9 ft 10 in]) from the parlour grand, or boudoir grand, (1.7 to 2.2 meters [5 ft 7 in–7 ft 3 in]) and the smaller baby grand piano (around 1.5 meters [4 ft 11 in]).[17]

All else being equal, longer pianos with longer strings have a larger, richer sound and lower inharmonicity of the strings. Inharmonicity is the degree to which the frequencies of overtones (known as partials or harmonics) sound sharp relative to whole multiples of the fundamental frequency.

This results from the grand piano's considerable string stiffness; as a struck string decays its harmonics vibrate, not from their termination, but from a point very slightly toward the centre (or more flexible part) of the string. The higher the partial, the further sharp it runs.

Acoustic Pianos with shorter and thicker string (i.e., small pianos with short string scales) have more inharmonicity. The greater the inharmonicity, the more the ear perceives it as the harshness of tone.

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 baby grand pianos satisfy the space and cost needs for domestic use; as well, they are used in some small teaching studios and smaller performance venues.
