US Patent:
20040025676, Feb 12, 2004
Filed:
Jun 5, 2003
Appl. No.:
10/454537
Inventors:
Warren Shadd - Forestville MD, US
International Classification:
G10H001/32
G10H003/00
US Classification:
084/743000
Abstract:
A high technology acoustic piano includes a piano body. A musical keyboard is mounted on the piano body. Keys are connected to the action for operating the hammers to strike strings. Strings adjacent to the hammers are arranged in different groups according to frequency, pitch, and ranges. A soundboard is mounted to the piano body and is spaced under the strings. Four or more pickups (located between the groups of strings and the soundboard) transmit frequencies, overtones and beats to onboard computers and to each pickup's separately controlled amplifier. An onboard computer mounts on the piano body near the musical keyboard and stores musical scores, written/drawn materials, and word processing text, and records music from the strings, pickups, modules, and amplifiers associated with the musical keyboard. A scanner slides from beneath the keyboard to copy printed/written/drawn materials and word processing text into the computer.
