Traditional sub-Saharan African harmony is a music theory of harmony in sub-Saharan African music based on the principles of homophonic parallelism (chords based around a leading melody that follow its rhythm and contour), homophonic polyphony (independent parts moving together), counter-melody (secondary melody) and ostinato-variation (variations based on a repeated theme).
In music theory, the key of a piece is the group of pitches, or scale, that forms the basis of a musical composition in Western classical music, art music, and pop music. Tonality (from "Tonic") or key: Music which uses the notes of a particular scale is said to be "in the key of" that scale or in the tonality of that scale. [1]
The key note, or tonic, of a piece of music is called note number one, the first step of (here), the ascending scale iii–IV–V. Chords built on several scale degrees are numbered likewise. Thus the chord progression E minor–F–G can be described as three–four–five, (or iii–IV–V).
The I–V–vi–IV progression, also known as the four-chord progression is a common chord progression popular across several genres of music. It uses the I, V, vi, and IV chords of a musical scale. For example, in the key of C major, this progression would be C–G–Am–F. [1] Rotations include: I–V–vi–IV : C–G–Am–F
The Oxford Companion to Music describes three interrelated uses of the term "music theory": The first is the "rudiments", that are needed to understand music notation (key signatures, time signatures, and rhythmic notation); the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology ...
A drop-2 voicing lowers the second voice by an octave. For example, a C-major triad has three "drop-2 voicings". Reading down from the top voice, they are C E G, E G C, and G C E, which can be heard as the voicings supporting the first three melody notes (following the introductory phrase) of the Super Mario Bros. video game theme.

Music theory is a set of systems for analyzing, classifying, and composing music and the elements of music.Narrowly it may be defined as the description in words of elements of music, and the interrelationship toward the notation of music and performance practice.
The universal key or universal scale is a concept employed in music theory in which specific notes or chord symbols in a key signature are replaced with numbers or Roman numerals, so that the relationships between notes or chords can be universally applied to any key signature.
