Do I really need music theory?
Music theory is about exploring the concepts that shape everything we play on the guitar. This section isn’t about memorizing rules; it’s about understanding why things sound the way they do, and how you can use that knowledge to play more intentionally, compose more creatively, and listen more deeply.
We’ll explore:
- Scales – patterns of inter-note information
- Modes – colors of the rainbow
- Chords – how harmony is built
- The Circle of Fifths – the best shortcut
In a clear, useful, guitar-focused way
Scales
In music theory, a scale, which comes from the Latin word scala meaning “ladder,” is a sequence of notes arranged according to a specific interval pattern. The way these intervals (such as whole steps and half steps) are organized determines the character of the scale. They typically consist of seven notes and cover a single octave. Each one represents a structure that carries musical meaning. Scales are the building blocks of melody, harmony, and tonality.
In this section, we will examine several commonly used types of scales: major, minor, pentatonic, whole tone, and chromatic.
We will also explain the concepts and functions of terms such as tonic, dominant, and subdominant.
