Fundamentals
The staff, the treble and bass clefs, line and space names, ledger lines, and where the key and time signatures sit, with a table to learn from.
Fundamentals
The major scale is seven notes spaced whole, whole, half, whole, whole, whole, half. Here is the formula, four scales built from it, and the sharps and flats it forces.
Rhythm & Meter
Each note value is half the one above it. Whole to sixteenth notes and their rests, plus how dots, ties and beams change what you count.
Guitar & Fretboard
Tab shows strings and frets rather than pitch names, and a chord diagram is a small grid of the same information. This explains both, with an arpeggio you can check against the fretboard.
Fundamentals
A major key has two close minor partners. The relative minor shares its key signature, the parallel minor shares its tonic, and each pair connects keys in a different way.
Harmony
Roman numerals label each chord by the scale degree of its root and its quality. Here is a step-by-step method, with I vi IV V worked in C and G.
Fundamentals
Scale degrees number each note of a scale from its tonic, and solfège names the same positions do, re, mi. Degree names, movable and fixed do, and why degrees travel between keys.
Songwriting & Composition
How verse, pre-chorus, chorus and bridge are arranged in common song forms, what each section is for, and how contrast makes the chorus land.
Harmony
A sus chord swaps the third of a triad for the second or fourth. Here is what Csus2 and Csus4 contain, why neither is major or minor, and how they resolve.
Fundamentals
Italian tempo words run from slow to fast. Approximate beats-per-minute bands for each, the modifiers and transitions that change them, and why a metronome number needs a time signature.
Acoustics & Sound
A vibrating string or air column sounds a fundamental and a set of partials at whole-number multiples of it. Here are the first sixteen, their cents, and where they differ from equal temperament.
Acoustics & Sound
Timbre is the shape of a note's spectrum: which partials are present, how strong they are and how the sound begins. Here is why a clarinet, a flute and a piano differ on the same pitch.
