- Musical form is the way sections are structured in a piece of music
- Sections are structured so as to combine into larger sections of music
- There is a relatively small number of kinds of formal design in music
- Most of the music created over all of time follows certain patterns of structural design
- This allows for analysis to be based on relativity to particular formal structures
- Rock and roll formal structures are limited to some basic concepts
- Understanding of form helps you to comprehend the listening examples discussed in this text
- Harmony Defined
- Scales identify tonality, referred to as a "key"
- There are twelve distinct scales in music
- Each scale is a set of ascending steps in a precise pattern of intervals from one note to the next
- An interval is the distance from one pitch to another
- The pattern is based on how many half-steps are involved to create an interval
- On a piano, a half-step (also called semitone) is the step from a white key to the black key next to it
- In Western European derived music, the semitone is the smallest pitch increment that can be played
- The set of intervals that generates a major scale is 2-2-1-2-2-2-1
- Starting from any pitch, the second pitch in a major scale is 2 semitones from the first starting pitch
- The third pitch is again two semitones above the second pitch
- The fourth pitch is only one semitone above the third pitch
- The fifth pitch is two semitones above the fourth pitch
- The sixth pitch is two semitones above the fifth pitch
- The seventh pitch is two semitones above the sixth pitch
- The next octave begins again one semitone above the seventh pitch
- Each scale degree is numbered from 1 to 7 as a point of reference
- All music scales are based on the first seven letters of the alphabet (ABCDEFG)
- There are two additional symbols that provide alterations of the pitches: sharps (#) and flats (b)
- Sharps raise a pitch by one semitone such that a C# sounds one semitone higher than a C
- Flats lower a pitch by one semitone such that a Gb sounds one semitone lower than a G
- A scale that begins on G would have a pattern of intervals that would produce the following scale: G-A-B-C-D-E-F#-G
- These pitches are the result of following the interval pattern 2-2-1-2-2-2-1
- The next to last note is an F# (not F) because that pitch must be 2 semitones above e
- F is only one semitone above E, so the next pitch must be used: which is F#
- Harmony is two or more notes sounding together
- Harmony in music is built around combinations of three-note simultaneous pitch groups called chords
- Chords are built on the pattern of combining notes found in a seven-note scale
- Chords are usually built out of combinations of three pitches from a scale
- These pitches are chosen based on a pattern of skipping one note in a scale and using the next note
- An example of this would be the scale of C, where the pitches are C-D-E-F-G-A-B-(C)
- The (C) is the beginning of the scale in the next octave as the scale continues upward
- The pitches C, E, and G would constitute a chord in that scale
- Another example of a chord in this scale would be the pitches F, A, and C
- Chords are numbered according to the degree of the scale on which they are built
- In the key of C, there are 7 possible chords, each built on one of the notes in the scale
- C=1, D=2, E=3, F=4, G=5, A=6, B=7
- To construct chords, simply combine three notes in a "skipped" pattern to generate these pitch groups:
- CEG, DFA, EGB, FAC, GBD, ACE, BDF
- Each set of three pitches is to be played together simultaneously to produce a chord
- Chords are represented by their position in a scale using Roman numerals
- There are three major chords represented by upper-case Roman numerals: I, IV, V
- Major chords sound "happy" because of the combination of intervals producing that particular chord
- In the key of C, the three major chords are CEG (i), FAC (iv), and GBD (v)
- There are three minor chords represented by lower-case Roman numerals: ii, iii. vi
- Minor chords sound "sad" because they consist of notes using a different set of intervals
- In the key of C, the three minor chords are DFA (ii), EGB (iii) and ACE (vi)
- There is also one chord (represented as vii°) that is unique, called a "diminished" chord
- The 12-Bar Blues
- Common structural pattern in much rhythm and blues
- Twelve groups of four-beat measures
- Divided into three groups of four measures each, called a "phrase"
- The first phrase often has a lyric that is repeated in the next phrase
- The last phrase provides a lyric that completes the thought
- A good example of a 12-bar blues in rhythm and blues is Joe Turner's "Shake, Rattle, and Roll"
- Same lyric occurs twice in a row for each of the first two phrases
- A new lyric appears in the last phrase
- Roman numerals indicate chords to be played in each numbered measure as follows:
- I IV I I IV IV I I V IV I V
- First phrase is the question, second phrase is the same question, third phrase is the answer
- By using this number system, musicians can simply apply the formula to any key (scale)
- The form of "Shake, Rattle, and Roll" is simple verse-chorus
- 12-bar blues is a pattern that is defined by its measure length, phrasing, lyrics, and chord structure
- Jackie Brenston's "Rocket 88" and Chuck Berry's "Johnny B. Goode" employ the 12-bar blues pattern
- "Johnny B. Goode" uses the 12-bar blues pattern and alternates verses and choruses
- "Rocket 88" uses the 12-bar blues pattern for verses only, thereby making it simple verse form
- Little Richard's "Tutti Frutti"
- Uses the 12-bar blues, but varies the progression in the last four bars of each verse
- Chorus: I I I I IV IV I I V IV I I
- Verse: I I I I IV IV I I I I I I
- Verse and Verse-Chorus Forms
- Simple verse-chorus form
- 12-bar blues is distinctive pattern used to build larger forms
- The relationship of the verses to the choruses
- A single pattern is used as the basis for both verses and choruses
- Can also consist of a repeating pattern that is not 12-bar blues
- Carter Family's "Can the Circle Be Unbroken" is built on a 16-bar progression
- It isn't a variation of the 12-bar blues pattern
- The verse and chorus use the same melody and harmony
- Only slight variations between the two
- The song is difficult to count because of numerous abnormalities in the number of beats in bars
- Simple Verse Form
- Song consists of only verses with no contrasting material that suggests a repeating chorus section
- "That's All Right" uses simple verse form
- Uses the chords found in 12-bar blues but not the pattern of the 12-bar blues progression
- Actually each section (verse) is 18 measures long
- "Heartbreak Hotel" is a clear example of simple verse form
- Each 8-bar verse based on the same chord progression
- An abbreviated version of the 12-bar blues
- Contrasting verse-chorus
- Verse section is distinctly different from the chorus section
- Can employ different chord progression
- Can employ different melody
- Can even use a different number of measures
- Chuck Berry's "Rock and Roll Music" is such an example
- 14-measure choruses
- 8-measure verses
- The chorus is the most memorable part of the song
- This tends to be the case with most verse-chorus forms (simple or contrasting)
- Buddy Holly's "That'll Be the Day" uses contrasting verse-chorus form
- 8-bar verse and chorus sections
- The instrumental bridge uses the 12-bar blues pattern
- AABA Form
- Song form most associated with mainstream pop
- Most common in the decades preceding rock and roll in Tin Pan Alley songs
- 32-bar structure that combines four 8-bar phrases
- AABA shows the pattern of 8-bar phrases
- The first two 8-bar phrases are very similar (AA)
- The third 8-bar phrase is contrasting (B)
- The last 8-bar phrase is similar to the first two (A)
- Some examples of songs that use this structure
- "Over the Rainbow"
- "I'm Sittin' on Top of the World"
- "Hey, Good Lookin'"
- "Blueberry Hill"
- Reprise
- Usually all or some part of the AABA pattern is repeated
- In a "full reprise" the entire AABA form is repeated
- In an "abbreviated reprise" part of the AABA form returns
- AABA can be expanded
- Jerry Lee Lewis's recording of "Great Balls of Fire" is a good rock and roll example
- The A sections are 8 measures long
- The bridge is 12 measures long
- The whole pattern is repeated
- Everly Brothers song "All I Have to Do Is Dream" uses 32-bar AABA with abbreviated reprise
- The overall form ends up being AABA* BA (the A* after the B section includes part of the intro)
- Notice that the song does not repeat the form in entirety, but is abbreviated
