The Answer is The term "key" in music refers to a group of pitches or scale degrees that form the basis of a musical composition. Each key is centered around a tonic note, which is the main pitch that the key is built upon, and it gives the piece a sense of home or resolution. The key of a piece determines the scale that will be used, which in turn influences the harmony, melody, and overall mood of the music.

Keys can be either major or minor, with each having a distinct set of intervals and emotional qualities. Major keys often sound bright and cheerful, while minor keys can sound more somber or melancholic.

Relating the key to the chromatic scale, the chromatic scale consists of 12 pitches, each a half step apart from the next. It includes all the notes of the piano within one octave: all the white keys and black keys. The chromatic scale is non-diatonic, meaning it does not belong to a specific key but includes all possible pitches.

When a key is established in a piece of music, it typically uses a subset of the chromatic scale. For example, the key of C major uses the seven pitches C, D, E, F, G, A, and B, which are all the white keys on the piano within one octave. These notes form the C major diatonic scale. Similarly, the key of G major uses the notes G, A, B, C, D, E, and F♯, which includes one black key (F♯) to maintain the specific pattern of whole and half steps characteristic of a major scale.

In essence, while the chromatic scale includes all possible notes, a key focuses on a specific subset of these notes to create a coherent musical structure. The notes outside of the key can still be used in a composition for various effects, such as creating tension or modulating to a different key, but they are not considered part of the key's primary scale.
