This segment deals with the shortest distance between chord roots. The concept is derived not only from the physical proximity of notes, but also from the desire and/or necessity to find the best possible chord outline while using limited range, which is particularly beneficial for playing at fast tempos.

These ten examples are based on ascending or descending lines from chord root G (various chord qualities) to chord root C. Notice that some lines are the same, e.g. G7#5 and Gmaj7 to C have the same ascending line (but not the same descending line). This is because the first notes (G A B) of the chord scales are the same but the descending notes of each chord scale are different.

Sometimes enharmonic equivalents have been used in the music notation for ease of reading. Generally, if it is not a chord scale tone, use sharps for ascending notes and flats for descending notes.

These five examples are longer phrases using the shortest distance between chord roots. Notice that where the root notes are less than a 4th apart, it is not possible to get a line without repeating notes. Therefore it is best to ascend or descend for three notes, then add a leading note on beat 4 within the region of ascent or descent. After playing these lines, try creating some of your own using the concept of shortest distance.
