- In the second half of the 18th century, the piano became the most used keyboard instrument, and composers of the Classical Era such as Joseph Haydn, Wolfgang Amadeus Mozart and Ludwig van Beethoven each wrote several piano concertos, and, to a lesser extent, violin concertos, and concertos for other instruments.
- Piano (Wikipedia)
The piano is a keyboard instrument that produces sound when pressed on the keys. Most modern pianos have a row of 88 black and white keys: 52 white keys for the notes of the C major scale (C, D, E, F, G, A, and B) and 36 shorter black keys raised above the white keys and set further back, for sharps and flats. This means that the piano can play 88 different pitches (or “notes”), spanning a range of a bit over seven octaves. The black keys are for the “accidentals” (F♯/G♭, G♯/A♭, A♯/B♭, C♯/D♭, and D♯/E♭), which are needed to play in all twelve keys.
- The invention of the piano is credited to Bartolomeo Cristofori (1655–1731) of Padua, Italy, who was employed by Ferdinando de’ Medici, Grand Prince of Tuscany, as the Keeper of the Instruments.
