The black keys are sharps and flats, and are located between the white keys. The sharps are to the right of the white keys, and the flats are to the left. The sharps and flats are named after the white keys they are located next to.
For example, the black key to the right of C is C#, and the black key to the left of D is Db.
The notes repeat in a pattern of octaves. Each octave is a set of 12 notes, including seven white keys and five black keys. The octaves are numbered from the lowest octave (number 1) to the highest octave (number 8).
Here are the notes of each octave:
- Octave 1: C, C#, D, D#, E, F, F#, G, G#, A, A#, B
- Octave 2: C, C#, D, D#, E, F, F#, G, G#, A, A#, B
- Octave 3: C, C#, D, D#, E, F, F#, G, G#, A, A#, B
- Octave 4 (the "middle octave"): C, C#, D, D#, E, F, F#, G, G#, A, A#, B
- Octave 5: C, C#, D, D#, E, F, F#, G, G#, A, A#, B
- Octave 6: C, C#, D, D#, E, F, F#, G, G#, A, A#, B
- Octave 7: C, C#, D, D#, E, F, F#, G, G#, A, A#, B
- Octave 8: C, C#, D, D#, E, F, F#, G, G#, A, A#, B
