1.Two keys that are adjacent to piano keyboard: The two keys that are adjacent to each other on a piano keyboard are called half steps.
2.Two keys that have another key in between: The two keys that have another key in between are called whole steps.
3.A half step written as two of the same note with different accidentals: This is called an enharmonic half step. For example, C# and Db are enharmonic half steps because they sound the same but are written differently.
4.A half step that uses two different note names: This is called a diatonic half step. For example, the distance between C and C# is a diatonic half step because it uses two different note names.
5.It is the stepwise arrangement of notes/pitches contained within an octave: This is called a scale.
II. Explanation
1.Scale relationships refer to the relationship between the notes in a particular scale. The most common scales used in Western music are the major and minor scales. The major scale has a specific sequence of whole steps and half steps, which are W-W-H-W-W-W-H (W = whole step, H = half step). The minor scale has a different sequence, which is W-H-W-W-H-W-W. Each note in the scale is assigned a number, or degree, based on its position in the scale. The tonic, or first note of the scale, is the most important note in determining the key of a piece of music.
2.C major is a specific scale that uses only the white keys on a piano keyboard. Its sequence of whole steps and half steps is W-W-H-W-W-W-H, starting from the note C. This means that the notes in the C major scale are C, D, E, F, G, A, B, and then back to C.
3.G major is another specific scale that uses both white and black keys on a piano keyboard. Its sequence of whole steps and half steps is W-W-H-W-W-H-W, starting from the note G. This means that the notes in the G major scale are G, A, B, C, D, E, F#, and then back to G.
