Question 1

What is the Circle of Fifths?

Accepted Answer

The Circle of Fifths is a visual representation of the relationships between the 12 tones of the chromatic scale. Each key is arranged a perfect fifth apart, making it easy to see which keys are closely related and understand key signatures, chord progressions, and modulation paths.

Question 2

What is a Tonnetz?

Accepted Answer

A Tonnetz (German for 'tone network') is a two-dimensional lattice diagram used in neo-Riemannian music theory. It arranges pitches so that horizontal movement represents fifths, vertical movement represents major thirds, and diagonal movement represents minor thirds. Triangles formed in the grid represent major and minor triads.

Question 3

What is Modal Interchange in music?

Accepted Answer

Modal Interchange (also called modal mixture) is the practice of borrowing chords from a parallel key. For example, in the key of C major, you might borrow chords from C minor to add harmonic color and surprise. Common borrowed chords include the iv, bVI, and bVII chords.

Question 4

What are chord voicings?

Accepted Answer

Chord voicings refer to the specific arrangement of notes within a chord, including which octave each note is in, which notes are doubled, and the spacing between notes. Different voicings of the same chord can create very different sounds and textures in music.

Question 5

How do chord progressions work?

Accepted Answer

Chord progressions are sequences of chords that form the harmonic foundation of a piece of music. They follow patterns based on the relationships between scale degrees (represented by Roman numerals like I, IV, V, vi). Common progressions like I-V-vi-IV are found across many popular songs.
