The Etude Generator: A Fresh Study, Written for Your Instrument, Every Single Time

Every serious musician has the same shelf. A stack of etude books — Arban, Rubank, Kopprasch, whatever your instrument's canon is — with the first fifteen pages worn soft and the rest untouched. You practiced the ones your teacher assigned, and the moment you'd learned an etude, it stopped being an etude. It became a piece you already knew. The whole point of a study is to read something you haven't seen, and a book can only be new once.

So we built the thing a book can't be: an etude that is genuinely new every time you open it. Not pulled from a library of a few hundred pre-written exercises that you'll eventually memorize too — composed on the spot, from scratch, for your instrument, in your key, at your level, aimed at the exact skill you're trying to build. The Virtuosic etude generator never runs out, never repeats, and — this is the part no book has ever done — it listens to you play it and tells you how you did.

It Composes. It Doesn't Retrieve.

This is the distinction that matters, so let me be precise about it. The etude generator is not a database of exercises with a shuffle button. It's a small, deliberate composition engine. When you tap generate, it plans a phrase structure — an eight-bar antecedent-and-consequent, a twelve-bar AA'B, a sixteen-bar double period — lays a functional harmonic progression under it (tonic to predominant to dominant and home again, the grammar every tonal piece is built on), then walks a melody across that harmony with real musical logic: contour arcs that rise and fall, chord tones landing on strong beats, leaps that resolve the way leaps are supposed to, a proper cadential approach into each phrase ending.

It knows your instrument, too — not as a label, but as a set of habits. It writes breathing rests into a wind part where a player would actually need to breathe. It gives a brass part a moment to recover after a taxing passage. On piano it writes a left-hand accompaniment under the melody. The result reads like something a thoughtful teacher wrote for you that morning, because the rules it follows are the same ones a teacher writing an etude would follow.

And it's rendered as real notation — actual engraved staves, beams, ties, slurs, accidentals, articulations, dynamics — not a piano-roll or a letter-name crib. You read it the way you'd read anything on your stand.

The Controls: Six Choices That Shape the Study

You don't have to touch any of these — sensible defaults are seeded from the instrument you're already using in the tuner — but each one is there when you want to aim the exercise at something specific.

Instrument. Flute, oboe, clarinet, bassoon, the whole saxophone family, trumpet, horn, trombone, euphonium, tuba, violin, viola, cello, bass, guitar, ukulele, voice, piano — the study is written in your instrument's written pitch and transposition, so a B♭ trumpet part looks like a trumpet part and an F horn part looks like a horn part.

Clef. Treble, bass, alto, or tenor. It defaults to the right clef for the instrument — bass for trombone and tuba, alto for viola — but a cellist working on tenor-clef reading can force the issue.

Key. All 24 — every major and every natural-minor key. This alone replaces a shelf of "studies in all keys" books, and unlike the book, it'll write you a fresh one in D♭ every day until D♭ stops scaring you.

Time signature. 4/4, 3/4, 2/4, 5/4, 6/8, 9/8, 12/8 — simple and compound, including the odd meter most method books barely touch.

Difficulty. Three tiers — Foundations, Developing, Advanced. This isn't just "more notes." It changes the rhythmic vocabulary, whether pickups and ties and slurs appear, how wide the melodic range runs, and how adventurous the harmony gets (deceptive cadences and borrowed chords only show up at the top tier).

Focus. This is my favorite control, because it turns the generator into a targeted tool instead of a random one. Pick the skill you're weak on — Rhythm, Arpeggios, Intervals, Articulation, Dynamics, or Range — and the engine biases the whole study toward it. Struggling with wide leaps? Focus on Intervals and it'll write you a study full of them. Not sure what you need? Leave it on Surprise me and it picks for you.

Length. Eight, twelve, or sixteen bars — a quick reading rep or a real page of work.

Tempo is chosen for you based on difficulty so the study is playable as written, and the comfortable range is derived from your instrument and level so a beginner's Foundations study never wanders into the altissimo. Set it and forget it, or fiddle with everything — both work.

Then It Listens

Here's where the generator stops being a fancy notation printer and becomes a practice partner.

Generate a study and you get two ways to play it. First, reference playback — tap play and hear the whole thing, both hands if it's a piano study, so you know how it's supposed to go before you attempt it.

Then the one that matters: Play Along. Tap it, pick your practice tempo — full speed, 90%, or a patient 75% for the first read — and after a count-in, play the etude while the app listens through your microphone. This runs on the same real-time pitch-detection engine that powers the main tuner, so it's not guessing. When you finish, the score re-renders with every notehead color-coded by how you actually played it: green for in tune, amber for close, red for a real miss, grey for a note you skipped. And it gives you the honest tally — how many notes you nailed out of the total, how many you played, your average deviation in cents.

This is the accountability that solo sight-reading practice has never had. On your own, you play through a study, sort of hit the notes, and tell yourself it counted. The play-along doesn't let you off that easy. It scores against every note, so skipping the hard bar shows up as a lower number, not a clean run. Ten minutes a day of this — read cold, play scored, see the red noteheads, run it again — is a completely different practice diet than "playing through" an exercise you can't objectively grade.

(One honest note: the play-along scores the melody line. On a grand-staff piano study the left hand plays as reference audio but isn't scored, because a single microphone can't reliably separate two hands. The right hand is where the reading skill lives, and that's what gets graded.)

Your Etudes, Kept

Every study you generate is logged under Your Etudes, split into Recent and ★ Favorites. Recent keeps your last studies on hand to re-run. Star the ones worth keeping and they're saved in full — even a favorite from an older version of the engine reloads exactly as it was.

When you find one you love, you can share it as an image, save it as a print-ready PDF, or print it outright — so the etude your teacher would've had to write by hand is a clean page on your stand in one tap. And because it all syncs to your account, the study you starred on your phone is waiting on your tablet, best score and all.

Speaking of scores: the generator tracks your best play-along percentage per study, so re-running a favorite is a measurable rematch, not a vague "that felt better." It also feeds the progress system — you earn XP for generating and for completing scored runs (with a daily cap so it stays honest), and there are achievements waiting: Etude Debut for your first play-along, Etude Virtuoso for a 90%-or-better run, Etude Marathon for twenty-five completed studies. If you're a Premium user, "Complete an etude play-along" also turns up as a daily challenge.

Where It Sits in the App

The etude generator isn't an island. It shares DNA with the rest of Virtuosic on purpose.

• It reaches for the tuner's pitch-detection engine to score you, and tunes its reference audio to whatever A-frequency you've set for your instrument.
• It's the reading-practice complement to the Learn tab's Sight Reading trainer — where Sight Reading drills short generated snippets, the etude generator hands you a full, structured study to work.
• Its output is the same notation format the Studio notation editor uses, which is why the two feel like one system.

What It Costs

The etude generator is a Premium feature, top to bottom — there's no partial free version, because a half-generated etude isn't worth shipping. Premium is $119.99 a year, and it also unlocks the AI practice coaching, unlimited Learn-tab rounds, the drone builder, and everything else on the analytics side. If you teach, the Studio tier includes all of it and lets you assign this kind of work to your students.

A Note From the Developer

I spent years buying etude books, learning the first quarter of each, and letting the rest gather dust — not because the studies were bad, but because a study you've memorized isn't a study anymore. The whole value is in the unfamiliar. So I wanted to build something that could hand a student an endless supply of unfamiliar-but-well-written material, in any key, aimed at any weakness, and then — the part I'm proudest of — actually listen and tell them the truth about how they played it. No book can do the second half. Now nothing's stopping you from reading something new, and playing it honestly, every single day.

Open the app, tap the Etude Generator, pick your key and your weak spot, and generate one. Read it cold. Then hit Play Along and find out how you really did.
