At-Etudes

Interactive Fretboard Logic

See the shapes. Hear the relationships. Understand the fretboard.

Explore the patterns that make melody and harmony work on the guitar — chords, scales, modes, intervals, and their relationships across the neck.

Each étude is a living, interactive fretboard study. Choose the harmony, shapes, and movement you want to explore, and the chart adapts to what you’re working on right now. This isn’t about memorizing more diagrams. It’s about seeing how the pieces connect and turning fretboard knowledge into musical instinct.

Study. Explore. Keep Track.

Every étude includes its own Journal, with a notepad and practice log for capturing discoveries, recording what you worked on, and tracking your progress over time.

AptÉtudes

Tools you shape: set the key, the position, the harmony and the motion, and the étude is whatever you built.

Metronome

The At-Etudes metronome, standing alone — three click voices, tap tempo, accents, subdivisions — with a notepad that saves every idea alongside the tempo it arrived at.

Multetudes — the Étude Designer

Build an étude from the ground up: frame a position on the neck, pick what sits on it — scale, dyad, triad, tetrad or shell — write the figure in slots or chord tones, run it through a progression, and hear it on the neck, the staff and the keys.

Triadetudes — the Triad Étude Designer

Design your own triad isolation étude: pick a key, a string set and three pivot notes; cycle triads through progressions with minimal voice movement; see it, hear it, log the practice.

Tetradetudes — the Tetrad Étude Designer

Four voices deep: close, drop-2 and drop-3 chords walking through progressions with minimal movement — arpeggiate them or enclose a target tone, then log the practice.
