Editing Comping (jazz) (section)

===Horns===
In small jazz ensembles ("combos") with more unusual instrumentation, horn players (e.g., saxophone, trumpet, etc.) can comp by playing the melody line in the background, or by playing a sequence of notes called "[[guide tone]]s" which outline the harmonic framework. Guide tones are usually the 3rd, 7th, or 9th notes of a given chord. Guide tone lines are constructed by descending (or ascending) through the guide tones of the chart, normally by semitone or tone. For instance, in a duo for [[saxophone]] and bass, the saxophonist might comp during the bass solo by playing guide tones.

For example, during the standard jazz chord progression ii7/V7/I/VI7 (in the key of C Major, this would be Dm7/G7/C/A7), a horn player might play the guide tones, in whole notes, C (minor 7th of d minor), B (third of G7), A (sixth of C; sixths are added to major chords in jazz even when not specified) and G (minor 7th of A7). This is only one possible guide tone sequence. A second guide tone sequence (in whole notes) might be F (minor third of d minor), E (sixth of G7), D (ninth of C Major; as with sixths, ninths are often added to chord voicings even when not indicated), C# (major third of A7).
