Parts of the Staff

  1. Clef - Indicates how to read the notes on the staff

  2. Key Signature - Indicates which pitches will be raised or lowered. 

  3. Time Signature - Tells us how many & of what note value go into each measure. 

  4. Barline - Splits the staff into measures based on the time signature. 

  5. Measure - A segment of music that has a certain number of beats. 

  6. Double Barline - Two lines that indicate the end of a piece.

Notes & Rhythm

Notes vs. Rests

  • Notes are beats of sound

  • Rests are beats of silence

Time Signatures 

Enharmonic - notes that are the same pitch but have a different name 

ex) 

  • In the chart below A# and Bb are the same pitch 

Special Cases 

  • B/C and E/F

Major Keys

Sharps 

Step 1

  • Remember the order of the sharps. The sharps will always show up in the same order.

Step 2

  • Look at the last sharp on the staff (the one farthest to the right).

Step 3

  • Take the name of that sharp and go up one half step (the very next note). That’s the name of the key!

    • Example: If the last sharp is C#, go up one half step → D major.

    • Example: If the last sharp is F#, go up one half step → G major.

Special Case

  • If there are no sharps, the key is C major!

    • If you C no sharps and C no flats it is the key of C major

Flats

Step 1

  • Remember the order of the flats. The flats will always show up in the same order.

Step 2

  • For flats, it’s not the last one—it’s the next-to-last flat (the one just before the last one on the staff). That’s the name of the key!

    • Example: If the flats are B♭, E♭, A♭, the second-to-last is E♭ → the key is E♭ major.

    • Example: If the flats are B♭, E♭, the second-to-last is B♭ → the key is B♭ major.

Special Cases

  • If there’s only one flat (B♭), the key is F major.

  • If there are no flats, the key is C major.

Modes

What is a mode?

  • "The word ‘mode’ comes from the Latin for ‘manner, or method’ but musical modes all originated in ancient Greece, so they have Greek names. The modes were named after various regions, perhaps to represent the people who lived there, because Greek musical theorists were philosophers too, and associated the arts with aspects of morality. Basically, a mode is a type of scale, as in ‘do re mi fa so la ti do’. Alter just one of those notes and you can call your scale a ‘mode’ (https://www.classicfm.com/discover-music/latest/guide-to-musical-modes)

 

Why do we use modes?

  • Modes help composers and musicians identify common patterns used. Various modes are famously used to play certain styles and can guide composers/musicians on how to add phrasing or how to write the next section.

Ionian = Major Scale

WWHWWWH

Aeolian = Minor Scale

WHWWHWW

Lydian = Major Scale w/Raised 4th

WWWHWWH

Mixolydian = Major Scale w/Lowered 7th

WWHWWHW

Dorian = Minor Scale w/Raised 6th

WHWWWHW

Phrygian = Minor Scale w/Lowered 2nd

HWWWHWW

Locrian = Minor Scale w/Lowered 2nd & 5th

HWWHWWW

If you play all white keys on the piano starting on C you have Ionian

Starting on:

C = Ionian

D = Dorian

E = Phrygian

F = Lydian

G = Mixolydian

A = Aeolian

B = Locrian
