Lessons in this unit

Pitch, the Major Scale & Key Signatures14 min · 3 objectivesName pitches and identify half steps and whole steps between them · Construct any major scale using the whole-and-half-step pattern · Determine a major key signature and place it on the circle of fifths
Rhythm & Meter13 min · 3 objectivesIdentify note and rest values and their proportional relationships · Distinguish simple from compound meter using the time signature · Determine how many beats a measure holds and how each beat divides

Formulas in Unit 1

Major scale step pattern

W – W – H – W – W – W – H (do re mi fa sol la ti do)

Half steps fall between degrees 3–4 (mi–fa) and 7–8 (ti–do). Every major scale, in any key, uses exactly this pattern.

Reading a compound time signature

beats = (top number) ÷ 3 · beat unit = dotted note · division = 3

For 6/8: 6 ÷ 3 = 2 beats (duple), each beat a dotted quarter dividing into three eighths. For 9/8: three beats; for 12/8: four beats.

What examiners penalize here

To name a sharp key fast, take the **last sharp and go up a half step** — that is the tonic (last sharp C♯ → tonic D). For flat keys, the **second-to-last flat is the tonic** (flats B♭ E♭ A♭ → tonic E♭). Memorizing these two tricks saves time on the exam.
Watch the classic trap: **3/4 and 6/8 both contain six eighth notes**, but 3/4 groups them as three beats of two (simple triple) and 6/8 as two beats of three (compound duple). The grouping — not the raw count of eighths — determines the meter and the felt pulse.

Practice Music Theory

Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
