This guide explains the concepts of chromatic and diatonic semitones, essential for music theory. A chromatic semitone involves notes with the same letter name, while a diatonic semitone consists of notes with different letter names. Simple memory aids, such as connecting "diatonic" with "different," help clarify these terms. The guide also provides step-by-step instructions for notating both types of semitones relative to any given note. Finally, it touches on enharmonic notes and the concept of whole tones, enhancing your understanding of musical distances.

A chromatic semitone uses notes with the same letter name. F G F F Chromatic Semitone Diatonic Semitone A diatonic semitone uses notes with different letter names. MEMORY HELP: “Diatonic” and “Different” begin with the same letters.
To write a note a chromatic semitone above a given note: C C Draw a note on the same line or space as the given note. Add an accidental to make the note a semitone higher than the given note.
To write a note a chromatic semitone below a given note: A A Draw a note on the same line or space as the given note. Add an accidental to make the note a semitone lower than the given note.
To write a note a diatonic semitone above a given note: C D Draw a note on the closest line or space above the given note. Add an accidental to make the note a semitone higher than the given note.
To write a note a diatonic semitone below a given note: A G Draw a note on the closest line or space below the given note. Add an accidental to make the note a semitone lower than the given note.
A whole tone is the distance of two semitones. WRITE IT RIGHT! 2 1 2 1 1 2 C D B Always use neighbour letter names to write whole tones. F G C
