A Sound, Musical Approach to Approach Notes
Approach notes can be a single note or single and double note combinations of chromatic and/ or scale tones which approach the target note from below and/ or above. They are sometimes referred to as "enclosures", since they tend to surround or enclose the intended target note.
Employing the use of approach notes is an important and time tested technique for creating tension and release within an improvised melodic line, through delayed resolution as well as basic ornamentation.
