3. Notation • Many cultures notate, or write down, their music in some way • Notation uses a complex set of symbols to represent pitch, duration, dynamics, expression, and so on • Even if you cannot read music, a basic knowledge of musical notation can help you follow along and understand concepts more easily

4. Pitch and Time • Just as on a graph: • Pitch measured vertically, from low to high • Time measured horizontally, from left to right

5. Rhythmic Notation • Note values • Note values express duration of notes • Durations are relative and proportional • A whole note equals two half notes; a half note equals two quarter notes; and so on • Names based on fractions of whole note (half, quarter, eighth, etc.) • Actual duration depends on tempo • White notes are longer than black notes • The more flags or beams, the shorter

6. Note Values

7. Flags and Beams • Flags and beams group together short notes within a beat • They make rhythms easier to read

8. Rests • Represent the silences between notes or phrases • Each note value has a corresponding rest, a silence of equal duration • Short rests have flags that correspond to the flags and beams of short notes

9. Rest Values

10. Dotted Rhythms • A dot placed after (to the right of) a note or rest makes it half again as long (150% of original) • Dotted rhythms mix longer dotted notes with shorter undotted notes

11. Ties • Any two or more notes (same pitch!) can be tied together to make one long duration

12. Legato • Slurs • Look like ties, but they connect two or more different pitches • Indicate that the performer must move smoothly from one note to the next, with no gap in the sound

13. Staccato • Staccato Dots • Dots placed above or below note heads indicate that the notes should be played staccato, in a detached manner • Musicians often play a staccato quarter note as if it were an eighth note followed by an eighth rest

14. Triplets • Notes normally divide into two or four equal parts • Triplets can be used to divide a note into three equal parts • Three notes are bracketed together and/or marked with the number 3 • Quarter note = two eighth notes = three eighth-note triplets

15. Meter • Measures • Basic time unit chosen for a piece of music • Vertical bar lines separate one measure from the next • Measures are normally equal in length

16. Meter • Time signatures • Found on the staff at the beginning of the piece • Top number = number of beats in each measure • Bottom number = note value of the beat

17. Pitch Notation • Seven letter names (ABCDEFG) assigned to seven original pitches of diatonic scale • Letter names re-used in every octave • Octaves often distinguished by numbers (c1 or c2) or prime marks (A’ or A”) • Middle C (c1) is just left of the middle of the keyboard, under the maker’s name

18. The Staff • To specify exact pitches, notes are placed on a five-lined staff • Notes can be placed on a line or in the spaces between lines • Ledger lines temporarily extend the number of lines in a staff when higher or lower notes are needed

19. Clefs • Clef signs at the beginning of each staff identify a reference pitch (G clef or F clef) • Clefs enable musicians to quickly identify specific pitches on any line or space • Most common are treble clef (G clef) and bass clef (F clef)

20. Clefs • Middle C is first ledger line above bass clef and first ledger line below treble clef • Since these clefs hardly overlap, they are often used together to notate a maximum span of pitches

21. Clefs • Piano music brackets treble and bass clefs together in a grand staff • With ledger lines, the grand staff can be used to notate every pitch on the piano keyboard

22. Sharps and Flats • Letter names identify the white keys on the piano keyboard • Sharps and flats are required to identify the black keys • In music notation, we write sharps and flats just to the left of a note head • In written prose or when speaking, we say the letter name first (C sharp or B flat)

23. Sharps and Flats

24. Sharps • To find a sharped note on the keyboard: • First find the white key for the letter name • Then find the key just above it (to the right!) • C sharp is the black key just above C • (B sharp is the white key just above B!)

25. Flats • To find a flatted note on the keyboard: • First find the white key for the letter name • Then find the key just below it (to the left!) • B flat is the black key just below B • (C flat is the white key just below C!)

26. Naturals • Naturals are used to cancel a sharp or a flat (to revert to the white key) • They are used when a sharped or flatted note is followed by a “normal” version of the same note • (Bar lines automatically cancel added sharps or flats)

27. Key Signatures • Most scales consistently use certain sharps or flats throughout a piece • Writing in those sharps or flats every time they appear takes time and adds clutter • Instead, composers put them in a key signature, found just after the clef at the beginning of each staff

28. Key Signatures • These two tunes sound the same, but the version with a key signature: • Looks nicer than the version without:

29. Scores • Music for a melody instrument (violin, trumpet, etc.) is written on a single staff

30. Scores • Music for keyboard instruments is written on two staves: one for each hand

31. Scores • Music for two or more instruments and/or voices is written in scores • Scores contain the music for every voice and instrument (every part) in a given piece • Parts are lined up vertically • In general, high sounding instruments go on top, low ones on the bottom

32. Scores • Scores can be simple, with just a few parts: • Or more complex (next slide):
