Three Multi-Pentatonic Sequences in Minor 3rds
One off the smoothest and most common of these "dot connectors" is the melodic resolution by a half or whole-step between harmonies.
This can be especially effective when dealing with a harmonic progression which doesn't resolve up or down in Perfect 4ths or 5ths (as does a ii-V7-I); moving instead in Major or minor 3rds, for example.
