• Structure & Formation of Triads (09:06) - Tom lays out the basic structure of root position triads (three note chords) and how these triads are derived from the major scale. Improvisation exercises are also suggested and demonstrated.

• Voicing Triads (10:17) - This video explores how triads can be voiced with the commonly used block chords, but also introduces more open choral style chords. Learning these open "voicings" is a vital step to growing one's harmonic vocabulary.

• Moving Between Triads (11:49) - Tom demonstrates and explores how the open voiced triads can move from one to another, creating aesthetically pleasing voice leading of a type found in styles ranging from classical to jazz to gospel to pop.

• Structure & Formation of Seventh Chords (11:01) - Tom now applies the concepts learned in the first triad video to seventh chords, which are chords made up of four notes derived from the major scale.

• Voicing Seventh Chords (07:30) - This video explores the various ways that seventh chords can be voiced in block style, and as above in open choral style. The role of the dominant chord is also explored.

• Moving Between Seventh Chords (12:09) - Movement between seventh chords is now explored in greater depth. Reaching this stage of this course opens up a new palette of harmonic possibilities!

• Concepts of Playing in 12 Keys (11:41) - Tom explains the circle of fifths and how this tool can be used to simplify the process of learning to play and think in different keys, utilizing the concepts learned in chapters 1 and 2.

• The Must Know I, IV & V Chords (09:50) - Tom now reveals the necessity of knowing the I, IV and V chords in different keys, and re-emphasizes that knowing these chords is greatly simplified by understanding how these chords are derived from the scale.

• Seeing Scales as Modes (10:32) - Furthering the simplification process, Tom explains and demonstrates how "seeing" the major scale of each key as a simple major mode (taking a minds-eye picture) opens up chordal and melodic thinking.

• Introducing the Minor System (08:39) - Tom explains the minor system and its derivation from the relative major scale, and introduces the first of the three minor scale types. The chords derived from the "natural" minor scale are explained and demonstrated with improvisation exercises.

• Harmonic Minor Scale & the Use of Discretion (10:59) - Tom simplifies the harmonic minor scale and explains and demonstrates the primary reason for and function of this scale. Reinforcing exercises and improvisations are also shown!

• Melodic Minor Scale & More on Discretion (12:56) - The melodic minor scale is now presented in this video, and the role of discretion in the minor system, such as using taste and aesthetic preference to explore the chordal and melodic options is further explored.
