Inversions of Triads & Triads on Various Scale Degrees

Triad Brain Teasers 1. Do all triads contain three notes? 2. A Triad can be simplified to a stack of __? ___(name interval). Name all the intervals a triad can contain. 3. Is any three-tone combination constructed of thirds a triad? Give a counter-example/exception if there is one. 4. In this triad, is the bottom note the bass tone? & ? 5. Give the formulas for constructing the four types of triads:

Naming Triads Give triad name, quality, root pos. or inversion. 1. Arrange as a stack of thirds in closed; root position (use shortcuts): eliminate doublings, memorize 7 triad letter names, spot 5 ths, 4 ths 2. Name Triad by its Root 3. Calculate the quality of thirds, which, in turn, gives triad quality 4. Determine if original is in root position or inversion (bass tone).

Inversions of Triads 1. Triad inversion depends only on the bass tone or lowest note. Root in Bass = Root Position 3 rd in Bass = 1 st Inversion 5 th in Bass = 2 nd Inversion 2. Triads retain their qualities (M, m, o, +) under inversion.

Triads on Various Scale Degrees I. General Memorize the Pattern for Major M I m III M IV M V m VI o VII M I II. Majors I, IV, and V are Major Chords (modal scale degrees). II, III, and VI are minor. VII = dim III. Minors Nearly all common harmonies use 6 and 7(LT)* *exception: III in minor normally uses f 7 (subtonic) Why?

Practice Problems In which major scales is this chord found? Given top voice, build triads down Given Bass tone, Quality, and figures, Construct the triad Given G= Root; build triad
