Baroque Ornamentation: Trills, Mordents and Turns
Execute trills, mordents, turns and appoggiaturas correctly: on-beat starts, national styles, and reading ornament tables.

Figured Bass: Reading Intervals Above the Bass Line
Figures name intervals above the bass, not chords. What each shorthand means, how accidentals override the key, and what the player decides.

Compound Meter: 6/8 vs 3/4 and How to Hear the Difference
Six eighth notes per bar can group as 3+3 in 6/8 or 2+2+2 in 3/4. Accent, contour, hemiola and conducting show which grouping you are hearing.

How to Read Sheet Music: Staves, Clefs and Note Names
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.

How to Write a Melody Over Chords, Note by Note
Put chord tones on strong beats, approach tension notes by step, and keep the line singable. A worked melody over C, G, Am and F shows each choice.
Rhythm & Meter
Meter, Beat Hierarchy and Hypermeter in Performance
Meter is a pattern of strong and weak positions, not a time signature: how it is built, how it stretches past the bar, and where performance contradicts it.
Rhythm & Meter
Time Signatures Explained: Simple, Compound and Beyond
A time signature gives beats per bar and the note value that counts as one beat. Simple meters split each beat in two, compound meters split it in three.

Tritone Substitution: The subV7 Chord That Still Resolves
Replace any dominant with the dominant a tritone away: why subV7 works, how it smooths bass lines, and where jazz standards hide it.
Music History
Gregorian Chant and Neumes: How Early Scribes Wrote Melody
Gregorian chant is unaccompanied Latin liturgical song. Neumes were the signs that recorded its melodies, first showing only the direction of movement and later placed on lines.

How to Transcribe Music by Ear: A Step-by-Step Procedure
Transcribe by ear in a fixed order: key and bass first, then chords by root and quality, then the melody by scale degree, and rhythm last.

Note Values, Rests, Ties and Dots Explained
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.

Odd Meters in 5/4 and 7/8: Counting, Feeling, Writing
Hear 5/4 and 7/8 as beat groups, not math: counting systems, conducting, repertoire from Brubeck to Balkan dance.
Counterpoint
Imitation and Invertible Counterpoint
Imitation makes one idea serve two lines. Invertible counterpoint makes those lines interchangeable, and the arithmetic behind it is small enough to check.

Polyrhythm and Cross-Rhythm: Counting the Distinction
Polyrhythm, cross-rhythm and polymeter are not interchangeable. Counting the ratios shows what separates a divided span from a pattern set against a metre.

Rhythm & Meter
Swing Timing: What the Notation Does Not Say
Jazz notation asks for swing and leaves the ratio to the players, because the timing is tempo-dependent and a fixed written value would be wrong at most speeds.
Guitar & Fretboard
Reading Guitar Tabs and Chord Diagrams for Beginners
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.
