  Percussion Atlas

  Percussion instrument reference

For teachers

Ready-to-assign teaching sequences

A Teaching Sequence is a free, ordered progression built from the apps. Choose a complete sequence or one assignment, copy the link into Google Classroom or Canvas, and students work under clear conditions without creating an account.

• Scale Trail · 8 steps

  Major Keys

  C, then band flats

  C as the on-ramp, then the keys your band actually plays. Eight trails, each with a pinned seed and a stated support level. Steps 2–4 match the Bronze scale-club keys.

• Mallet Map · 10 steps

  Naming Notes

  Treble staff, on the keyboard

  Spaces before lines, the staff before ledger lines, then sharps, flats, and the bar with two names. Each step pins its own notes, label policy and seed.

  See the steps →

• Count It · 10 steps

  Counting Rhythms

  4/4, straight subdivisions

  Quarters and pairs, rest entry, sixteenths in stages, then full measures with the guide off. Each step pins its rhythms, the subdivision guide and a seed.

• Count It · 6 steps live

  Rhythms in Three

  3/4 and 3/8, two spellings of one thing

  Three beats instead of four, then the same bar with the eighth taking the beat. The 3/4 steps open in Count It; the 3/8 steps open in its sibling app, Eight Time.

  Real notation, both hands

• Staff Spot · 9 sequences, 36 levels

  Reading the Staff

  Treble, bass, and both at once

  Nine short ladders of four levels each, picked by clef and skill rather than worked end to end: lines and spaces, ledger notes, accidentals, building notes from their names, and keeping the clef in mind when the staff changes.

The whole topic, every way you need it

Every Theory Reference poster has a written lesson behind it, and there are nineteen topics in all. Eighteen carry two ready-to-teach plans — forty-five minutes for a first teach, twenty for a review — and there is a printable worksheet with its answer key, or an app drill, wherever one exists. Nothing needs an account.

  Theory Lessons

  Poster, lesson, worksheet, drill

  The keyboard family; grip, stance and stroke; tone and mallet choice; keyboard map and enharmonics; keyboard interval shapes and two-mallet motion; reading across the keyboard; build and play a major scale; note names; note and rest values; sixteenth rhythms; rhythms in three; the staff; dynamics; tempo terms; rolls and marks; time signatures; the grand staff; triplets; and the rudiments. Eleven are drawn from the same notation as the Theory Reference poster on your wall; the other two carry artwork of their own.

  Teacher Plans

  Notice, model, practice, check

  Eighteen topics carry a first-teach plan and a review plan each. Every block is timed, names the material it uses, and says what counts as proficient — with the standards it supports behind a toggle so the printed sheet stays a teaching document.
