Rhythm & Meter
A triplet fits three notes into the time of two of the same value. This article covers the ratio, the counts and how triplets differ from compound meter.
Acoustics & Sound
Separate time sampling from amplitude precision, choose a format for a real recording task and avoid mistaking larger files for recovered audio detail.
Acoustics & Sound
Budget an uncompressed audio export from seconds, sample rate, stored bits and channels, then scale it to stems without double-counting stereo.
Fundamentals
Dynamics set how loud a passage is, relative to its surroundings. Articulations set how each note starts and ends. This guide defines the common marks.
Guitar & Fretboard
A barre chord is an open chord moved up the neck. The E shape and the A shape are the two to learn first, and each one is built from its open chord by a simple rule of offsets.
Guitar & Fretboard
A capo raises every open string by one semitone per fret, so a G shape played at fret 2 sounds in A. This shows how to find the sounding key and how to choose a capo position.
Harmony
A chord symbol names the root, the quality, the extra notes and the bass. Here is how to read Cmaj7, C7, Cm7, C/E and C7b9, and the notes each one contains.
Songwriting & Composition
The chord loops that songwriters reuse most, in Roman numerals and in the keys of C and G, with the reasons they work and how to vary them.
Harmony
Diatonic chords are the triads built on each scale degree from the key's own notes. Here are their qualities in major and minor, worked out in C and A.
Ear Training & Practice
Interval recognition comes faster with a method: three intervals tied to a tonic, sung before they are named, and a short daily routine you can keep.
Music History
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.
Guitar & Fretboard
Every fret is one semitone, so the fretboard is a grid of note names. This covers standard tuning, the landmark frets and a two-week routine for learning the whole neck.
