Is there a shortest path to proficiency?

  • Competencies can be measured to form irregular topologies.

  • ShedLab records and maps latency data in real-time and generates practice sequences that target the frontier between mastered and not-yet-mastered material.

  • The sequences are generated by pathfinding for marks through real jazz literature.

ShedLab has a measurable effect on your ROI

ShedLab is designed to identify and eliminate your weaknesses very quickly, and provide receipts.

You can use it to:

  • Avoid practicing already-mastered material
  • Practice the canonical progressions that use your frontier vocabulary
  • Measure progress to substantiate your time investment
  • Optimize pace and outsource selection
Adaptive, prioritized attention

Low overhead, high quality practice

Under the Hood
  • Multi-factor probability weighting
  • Jazz literature corpus analysis
  • Real-time latency modeling
  • Skill tree progression gates
  • Success rate smoothing
  • Spaced repetition management
  • Fancy maths and stuff

Methodology

01 — Skill Tree

Hierarchical Grouping

Voicings, and their inversions, are organized into domains—Major 7, Dominant 7, Altered Dominants, Quartal, etc.

You can use the ShedLab jazz piano skill tree, or make your own for any discipline.

Content can be soft or hard gated

02 — Probability Engine

Weighted Selection

Not just what you're bad at, but what practice will yield the biggest improvement. Each attempt updates the model, generating sequences optimized for learning velocity.

  • Latency — slower responses increase selection probability
  • Realness — sequences reflect actual jazz literature progressions
  • Volatility — inconsistent times can signal approaching mastery
  • Recency — recent items may be suppressed or boosted
  • Circle of fifths adjacency, register diversity, and more

03 — You

Self-directed model

Trust a system that has your discernment built in

Set your own latency targets

Only practice stuff you want

The ShedLab engine has configurable & extensible practice scope, passing requirements, aspect tracking, etc.

04 — Telemetry

Obsessive measurement

Track your progress over time. Filter by keys, qualities, inversions, or whatever you need
