Grand Piano 101: Useful Resources

Introduction to Grand Pianos
There are various types of pianos and the best / grand-est of them of all is the Gran Piano, the ones which you see in movies and something that you find at the homes of the rich and the famous. These are also used by concert pianists and is a common display at popular performance venues.

The action lies beneath the strings, and uses gravity to return to a state of rest, which makes it easier to play faster repetitive notes, something which the masters would any day prefer.
In terms of size, the concert grands are around 7–10 feet, the parlor grand or boudoir grand are around 6–7 feet, and the smaller baby grand is around 5 feet long. The lengthier ones sound better but are much more expensive compared to the baby grands.

These are available in acoustic as well as the digital versions, with the later ones more commonly found in homes.
