the colour tones - before resolving later in the phrase to a 7th chord tone. In bebop the 9th, 11th and 13th notes were often altered by adding sharps or flats to these notes. Ninths could be flatted or sharpened. Elevenths were typically played sharpened. Thirteenths were often played flat. Enclosure is the use of scale tone(s) above the targeted note and chromatic tone(s) below, or scale tone(s) below and chromatic tone(s) above. "Flat 9" theory Another technique in jazz improvisation used by Parker is known "three to flat nine". These numbers refer to degrees of the scale above the root note of a given chord in a chord progression. This is a bebop approach similar to targeting. This technique can be used over any dominant chord that can be treated as a flat nine (b9) dominant chord. It entails moving from the third of a dominant chord, to the flat nine of a dominant chord, by skipping directly to the ninth, or by a diminished arpeggio (ascending: 3rd, 5th 7th, 9th). The chord often resolves to a major chord a perfect fourth away. For example, the third of a G7 chord is B, while the flat ninth is A. The chord resolves to C and the note A leads to G. Pentatonics Pentatonic scales are also commonly used in jazz improvisation, drawing perhaps from their use in the blues. Saxophone player John Coltrane used pentatonics extensively. Most scales are made up of seven notes: (in the key of C – the major scale) C D E F G A B). The major pentatonic scale comprises only five notes of the major scale (C pentatonic scale is C D E G A), whereas the minor pentatonic scale comprises the five notes (C E F G B). Pentatonics are useful in pattern form and that is how they are usually played. One pattern using the pentatonic scale could be 3 6 5 2 3 5 (in C: E A G D E G). Pentatonic scales also became popular in rock music, jazz fusion and electric blues. Cells and lines Lines (also known as licks) are pre-planned ideas the artist plays over and over during an improvised solo. Lines can be obtained by listening to jazz records and transcribing what the professionals play during their solos. Transcribing is putting what you hear in a record onto music paper. Cells are short musical
