Turnaround (music)
In jazz, a turnaround is a passage at the end of a section which leads to the next section. This next section is most often the repetition of the previous section or the entire piece or song.Randel, Don Michael (2002). ''The Harvard Concise Dictionary of Music and Musicians''. . p.693 The turnaround may lead back to this section either harmonically, as a chord progression, or melodically. Typical examples Typical turnarounds in jazz include: *I–vi–ii–V ( ii–V–I turnaround, circle progression) *I-VI-ii-V *I–VI–II–V (I–V/ii–V/V–V) *I–iii–ii7–V7 *I–vi–VI711–V * V–IV–I (blues turnaround) *I–III–VI–II7 (Tadd Dameron turnaround) *iii-VI-ii-V Turnarounds typically begin with the tonic (I) (or a tonic substitute such as iii) and end on the dominant (V7), the next section starting on the tonic (I). They may also end on II7 (which is a dominant substitute). Thus when used in a twelve bar blues pattern, the twelfth bar may end on the do ...

Tadd Dameron Turnaround
In jazz, the Tadd Dameron turnaround, named for Tadd Dameron, "is a very common turnaround in the jazz idiom",Coker, et al (1982). ''Patterns for Jazz: A Theory Text for Jazz Composition and Improvisation'', p.118. . derived from a typical I−vi−ii−V turnaround through the application of tritone substitution of all but the first chord, thus yielding, in C major: rather than the more conventional: The Tadd Dameron turnaround may feature major seventh chords, and derive from the following series of substitutions, each altering the chord quality:Bahha and Rollins (2005). ''Jazzology'', p.103. .Richard Lawn, Jeffrey L. Hellmer (1996). ''Jazz: Theory and Practice'', p.118-19. . The last step, changing to the major seventh chord, is optional. Dameron was the first composer to use the turnaround in his standard " Lady Bird", which contains a modulation down a major third (from C to A). This key relation is also implied by the first and third chord of the turnaround ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Approach Chord
In music, an approach chord (also chromatic approach chord and dominant approach chord) is a chord one half-step higher or lower than the goal, especially in the context of turnarounds and cycle-of-fourths progressions, for example the two bar 50s progression: , G / Em / , Am / D7 / , , may be filled in with approach chords: , G F9 Em Abm , Am D#7 D7 Gb7 , , F9 being the half-step to Em, Am being the half-step to Am, D7 being the half-step to D7, and G7 being the half-step to G. G being I, Em being vi, Am being ii, and D7 being V7 (see ii-V-I turnaround and circle progression). An approach chord may also be the chord immediately preceding the target chord such as the subdominant (F Maj7) preceding the tonic (CMaj7) creating a strong cadence through the contrast of no more than two common tones: ''FA''CE – CE''GB''. Approach chords may thus be a semitone or a fifth or fourth from their target. Approach chords create the harmonic space of the modes ...

Half Step
A semitone, also called a half step or a half tone, is the smallest musical interval commonly used in Western tonal music, and it is considered the most dissonant when sounded harmonically. It is defined as the interval between two adjacent notes in a 12-tone scale. For example, C is adjacent to C; the interval between them is a semitone. In a 12-note approximately equally divided scale, any interval can be defined in terms of an appropriate number of semitones (e.g. a whole tone or major second is 2 semitones wide, a major third 4 semitones, and a perfect fifth 7 semitones. In music theory, a distinction is made between a diatonic semitone, or minor second (an interval encompassing two different staff positions, e.g. from C to D) and a chromatic semitone or augmented unison (an interval between two notes at the same staff position, e.g. from C to C). These are enharmonically equivalent when twelve-tone equal temperament is used, but are not the same thing in meantone temp ...

Tritone
In music theory, the tritone is defined as a musical interval composed of three adjacent whole tones (six semitones). For instance, the interval from F up to the B above it (in short, F–B) is a tritone as it can be decomposed into the three adjacent whole tones F–G, G–A, and A–B. Narrowly defined, each of these whole tones must be a step in the scale, so by this definition, within a diatonic scale there is only one tritone for each octave. For instance, the above-mentioned interval F–B is the only tritone formed from the notes of the C major scale. More broadly, a tritone is also commonly defined as any interval with a width of three whole tones (spanning six semitones in the chromatic scale), regardless of scale degrees. According to this definition, a diatonic scale contains two tritones for each octave. For instance, the above-mentioned C major scale contains the tritones F–B (from F to the B above it, also called augmented fourth) and B–F (from B to the F above ...

Tritone Substitution
The tritone substitution is a common chord substitution found in both jazz and classical music. Where jazz is concerned, it was the precursor to more complex substitution patterns like Coltrane changes. Tritone substitutions are sometimes used in improvisation—often to create tension during a solo. Though examples of the tritone substitution, known in the classical world as an augmented sixth chord, can be found extensively in classical music since the Renaissance period, they were not heard until much later in jazz by musicians such as Dizzy Gillespie and Charlie Parker in the 1940s, as well as Duke Ellington, Art Tatum, Coleman Hawkins, Roy Eldridge and Benny Goodman. The tritone substitution can be performed by exchanging a dominant seventh chord for another dominant seven chord which is a tritone away from it. For example, in the key of C major one can use D7 instead of G7. (D is a tritone away from G). Summary In tonal music, a conventional perfect cadence consis ...

Neapolitan Chord
In Classical music theory, a Neapolitan chord (or simply a "Neapolitan") is a major chord built on the lowered ( flatted) second (supertonic) scale degree. In Schenkerian analysis, it is known as a Phrygian II, since in minor scales the chord is built on the notes of the corresponding Phrygian mode. Although it is sometimes indicated by an "N" rather than a "II", some analysts prefer the latter because it indicates the relation of this chord to the supertonic. The Neapolitan chord does not fall into the categories of mixture or tonicization. Moreover, even Schenkerians like Carl Schachter do not consider this chord as a sign for a shift to the Phrygian mode. Therefore, like the augmented sixth chords it should be assigned to a separate category of chromatic alteration. In European Classical music, the Neapolitan most commonly occurs in first inversion so that it is notated either as II6 or N6 and normally referred to as a Neapolitan sixth chord. In C major or C minor, for exampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Dominant
A secondary chord is an analytical label for a specific harmonic device that is prevalent in the tonal idiom of Western music beginning in the common practice period: the use of diatonic functions for tonicization. Secondary chords are a type of altered or borrowed chord, chords that are not part of the music piece's key. They are the most common sort of altered chord in tonal music. Secondary chords are referred to by the function they have and the key or chord in which they function. Conventionally, they are written with the notation "''function''/''key''". Thus, the most common secondary chord, the dominant of the dominant, is written "V/V" and read as "five of five" or "the dominant of the dominant". The major or minor triad on any diatonic scale degree may have any secondary function applied to it; secondary functions may even be applied to diminished triads in some special circumstances. Secondary chords were not used until the Baroque period and are found more fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minor Sixth
In Western classical music, a minor sixth is a musical interval encompassing six staff positions (see Interval number for more details), and is one of two commonly occurring sixths (the other one being the major sixth). It is qualified as ''minor'' because it is the smaller of the two: the minor sixth spans eight semitones, the major sixth nine. For example, the interval from A to F is a minor sixth, as the note F lies eight semitones above A, and there are six staff positions from A to F. Diminished and augmented sixths span the same number of staff positions, but consist of a different number of semitones (seven and ten respectively). Equal temperament In 12-tone equal temperament (12-ET), the minor sixth is enharmonically equivalent to the augmented fifth. It occurs in first inversion major and dominant seventh chords and second inversion minor chords. It is equal to eight semitones, i.e. a ratio of 28/12:1 or simplified to 22/3:1 (about 1.587), or 800 cents. Just t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minor Seventh
In music theory, a minor seventh is one of two musical intervals that span seven staff positions. It is ''minor'' because it is the smaller of the two sevenths, spanning ten semitones. The major seventh spans eleven. For example, the interval from A to G is a minor seventh, as the note G lies ten semitones above A, and there are seven staff positions from A to G. Diminished and augmented sevenths span the same number of staff positions, but consist of a different number of semitones (nine and twelve, respectively). Minor seventh intervals rarely feature in melodies (and especially in their openings) but occur more often than major sevenths. The best-known example, in part due to its frequent use in theory classes, is found between the first two words of the phrase "There's a place for us" in the song " Somewhere" in ''West Side Story''.Neely, Blake (2009). ''Piano For Dummies'', p.201. . Another well-known example occurs between the first two notes of the introduction to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seventh Chord
A seventh chord is a chord consisting of a triad plus a note forming an interval of a seventh above the chord's root. When not otherwise specified, a "seventh chord" usually means a dominant seventh chord: a major triad together with a minor seventh. However, a variety of sevenths may be added to a variety of triads, resulting in many different types of seventh chords. In its earliest usage, the seventh was introduced solely as an embellishing or nonchord tone. The seventh destabilized the triad, and allowed the composer to emphasize movement in a given direction. As time passed and the collective ear of the western world became more accustomed to dissonance, the seventh was allowed to become a part of the chord itself, and in some modern music, jazz in particular, nearly every chord is a seventh chord. Additionally, the general acceptance of equal temperament during the 19th century reduced the dissonance of some earlier forms of sevenths. Classification Most tex ...

Twelve Bar Blues
The 12-bar blues (or blues changes) is one of the most prominent chord progressions in popular music. The blues progression has a distinctive form in lyrics, phrase, chord structure, and duration. In its basic form, it is predominantly based on the I, IV, and V chords of a key. Mastery of the blues and rhythm changes are "critical elements for building a jazz repertoire". Background The blues originated from a combination of work songs, spirituals, and early southern country music. The music was passed down through oral tradition. It was first written down by W. C. Handy, an African American composer and band leader. Its popularity led to the creation of "race records" and the popularity of blues singers like Bessie Smith and Ma Rainy. The style of music heard on race records was later called "rhythm and blues" (R & B). As the music became more popular, more people wanted to perform it. General patterns that existed in the blues were formalized, one of these being the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
