What is the full range of a modern piano?

The full range of a modern piano indeed extends from A0 to C8. This range encompasses 88 keys, with A0 being the lowest note and C8 the highest. The piano keyboard consists of both the white and black keys, allowing for a wide variety of pitches and tonal colors. Each octave contains seven natural notes and five accidentals, leading to the extensive range characterized by a modern concert grand piano.

Understanding the full range is essential for composers, performers, and students, as it highlights the instrument's versatility in different musical contexts, from classical compositions to contemporary works. Recognizing that A0 is the lowest pitch on the keyboard and C8 is the highest helps musicians visualize the breadth of sounds available to them.

The other options reflect narrowed ranges that do not represent the complete span of the instrument, emphasizing the importance of recognizing the full capabilities of a modern piano.
