AP Music Theory Unit 1 Visual Review
A topic-by-topic visual walkthrough of Unit 1: pitch notation, rhythmic values, half and whole steps, major scales and keys, meter, and expressive markings.

UNIT 1 · TOPIC 1.1
Pitch and pitch notation
Notes live on the five lines and four spaces of a staff, fixed by a clef.
THE TREBLE STAFF
E G B D F
Lines, bottom to top: E G B D F ("Every Good Boy Does Fine")
Spaces, bottom to top: F A C E (they spell "FACE")
READING PITCH
The clef anchors the letter names.
Treble (G clef) for higher voices;
bass (F clef) for lower ones.
Ledger lines extend the staff for
notes above or below it.
Middle C sits on a ledger line between
the two staves.
KEY IDEA The clef fixes the letter names; lines and spaces do the rest.

Rhythmic values
Each note value lasts half as long as the one before it.
whole 4 beats
half 2 beats
quarter 1 beat
eighth ½ beat
sixteenth ¼ beat
RESTS AND DOTS
Every note value has a matching rest (silence). A dot adds half the note's value: a dotted half = 3 beats.
KEY IDEA Note values halve at each step; a dot adds half again.

UNIT 1 · TOPIC 1.3
Half steps and whole steps
The smallest distance on the keyboard is a half step; two of them make a whole step.
C D E F G A B C
whole step
half step
READING THE KEYBOARD
Half step: the very next key, white or black.
Whole step: skip one key between them.
The only natural half steps are
E to F and B to C (no black key between).
KEY IDEA Half step = adjacent key; whole step = two half steps. E to F and B to C are the natural half steps.

UNIT 1 · TOPIC 1.4
Major scales and scale degrees
Every major scale follows one step pattern, and each degree has a name and a role.
THE MAJOR STEP PATTERN · W W H W W W H
C D E F G A B C
W W H W W W H
C major uses only white keys, so its pattern is the clearest to see.
SCALE DEGREE NAMES
1 Tonic 2 Supertonic 3 Mediant 4 Subdominant
5 Dominant 6 Submediant 7 Leading tone
The tonic (1) is home; the leading tone (7) is a half step below it and pulls strongly back to 1.
KEY IDEA W W H W W W H builds any major scale; degree 1 is home, degree 7 leads back to it.

UNIT 1 · TOPIC 1.5
Major keys and key signatures
The circle of fifths orders every key by how many sharps or flats it carries.
C G D A E B
F♯ D♭ A♭ E♭ B♭ F
sharps →
← flats
ORDER OF ACCIDENTALS
Sharps: F C G D A E B
Flats: B E A D G C F (the reverse)
Clockwise adds a sharp; counterclockwise adds a flat.
NAMING A KEY FAST
Sharp keys: the tonic is a half step above the last sharp .
Flat keys: the tonic is the second-to-last flat .
KEY IDEA The circle of fifths lays out every key; sharps and flats always appear in a fixed order.

UNIT 1 · TOPIC 1.6
Simple and compound beat division
The difference is simple: does the beat split into two or into three?
SIMPLE · BEAT ÷ 2
1 beat
two eighths
The beat is a plain note (like a quarter).
Count "1 and 2 and".
Time signatures: 2/4, 3/4, 4/4.
COMPOUND · BEAT ÷ 3
dotted beat
three eighths
The beat is a dotted note.
Count "1 la li 2 la li".
Time signatures: 6/8, 9/8, 12/8.
KEY IDEA Simple meter divides the beat into two; compound divides it into three.

UNIT 1 · TOPIC 1.7
Meter and time signatures
The two stacked numbers tell you how many beats per measure and which note is the beat.
4 4
top number = beats per measure
bottom number = the beat's note value
4/4: four quarter-note beats per bar
COMMON METERS
2/4 duple · strong-weak
3/4 triple · a waltz feel
4/4 quadruple · "common time"
6/8 compound duple · two dotted beats
A bottom "4" means the quarter note gets
the beat; an "8" means the eighth note does.
KEY IDEA Top number counts the beats; bottom number names the beat's note value.

UNIT 1 · TOPIC 1.8
Rhythmic patterns
Beams, ties, dots, and syncopation shape how a rhythm is grouped and felt.
HOW NOTES GROUP
Beaming connects eighths and shorter
notes so each beat is easy to see.
A tie joins two notes into one longer
sound across a beat or bar line.
A dot lengthens a note by half its value.
Clear beaming keeps every beat readable.
SYNCOPATION
the tie pushes the accent off the beat
Syncopation stresses a weak beat or an
offbeat, often with a tie or rest, giving
the music its "pushed" feel.
KEY IDEA Beaming shows the beat; ties, dots, and syncopation stretch and shift it.

UNIT 1 · TOPIC 1.9
Tempo
Tempo is the speed of the beat, named with Italian terms and measured in beats per minute.
Largo Adagio Andante Moderato Allegro Presto
~50 ~70 ~92 ~112 ~130 ~180
slower ← beats per minute (BPM) → faster
CHANGING SPEED
accelerando gradually speeds up · ritardando gradually slows down
a tempo returns to the original speed · fermata holds a note beyond its value
KEY IDEA Italian terms name the tempo; BPM measures it; accel. and rit. change it.

UNIT 1 · TOPIC 1.10
Dynamics and articulation
Dynamics control how loud; articulation controls how each note is attacked and released.
DYNAMICS · SOFT TO LOUD
pp p mp mf f ff
p = piano (soft), f = forte (loud);
m = mezzo (medium).
crescendo grows louder;
decrescendo grows softer.
ARTICULATION
staccato (dot): short, detached
accent (>): emphasize the attack
slur : play smoothly (legato)
fermata : hold the note longer
KEY IDEA Dynamics set the volume; articulation marks shape each note's attack and length.
