Chapter 4
In this section, we focus on the F♯ tonic position. The other four black tonic positions will be discussed in the flat (♭) section.
When the tonic of a major key shifts from a white key to its sharp (♯) position, all notes in the key move forward one position (e.g., B♭ becomes B).
Rule for Identifying Sharp (♯) Key Signatures
Add seven to the natural white tonic's position value on the Rectangle of Fifths.
For example, -1 plus 7 equals six sharps (♯).
Important Note:
Each note in a key has a scale degree between one and seven, not to be confused with keyboard position values.
In major keys, major chords are found at scale degrees 1, 4, and 5
Recognizing Major Fourth and Fifth Notes
Tonic:
The tonic is the starting note of the key.
Major Fourth (Subdominant):
The major fourth is one keyboard position below the tonic.
Major Fifth (Dominant):
The major fifth is one keyboard position above the tonic.
Chords
The third note of a chord will be one value higher than the root note value.
Major sharp chords add brightness and tension to music compositions, enhancing harmonic progressions and dynamic shifts.
