Today I’ve posted a more advanced tutorial on harmony and in particular the harmonic extensions and voicings used in Jazz.
The “pretty notes” as Charlie Parker called them, are the higher notes of the chords (9th,11th,13th) which are vital to contemporary Jazz but also familiar to classical musicians from the works of Debussy and Ravel.

It’s important to be able to instantly recognize these larger intervals in every key as well as to utilize them properly by means of good “voicing”.
To Jazz and commercial musicians “voicing” is the way that one places the notes of the chord across the keyboard (or among the instruments if arranging) and really, is of more importance than the simple choice of notes in the chord.
