Étude — Loop & Slow Down YouTube for Practice Firefox

Étude — Loop & Slow Down YouTube for Practice

Practice tools for YouTube — loop a section, slow it down, zoom in for precision. Made for musicians learning by ear.

Features & Capabilities

Built for musicians learning by ear — and anyone who needs to study a passage of video closely.

PRACTICE TOOLS, BUILT AROUND LOOP REGIONS • Set a loop region with draggable handles right on the YouTube timeline • Loop it — or drill it one-shot at a time: playback pauses at the end of the region, press play (or space) to run it again from the top • Slow playback from 0.25× to 3× in 0.25× steps; click the readout to snap back to 1×

ZOOM IN FOR PRECISION Open the zoom panel to expand your loop region into a magnified timeline. Place the start and end exactly where they belong — down to the split second.

MARK THE TROUBLE SPOTS Shift-click the zoomed timeline to drop practice marks inside your loop. Click a mark and the loop plays from that point to the end — drill the hard bit, then click it off to run the whole passage again. Shift-click a mark to remove it.

CHANGE THE KEY — NOT THE TEMPO Transpose the song up or down by up to 12 semitones without slowing it down. Match a song to your voice or to your instrument's tuning, or shift a lick into an easier position — then hold Shift to fine-tune by cents.

COUNT YOURSELF IN A metronome counts you in before the loop starts, so you come in on time instead of scrambling. Tap the tempo or drag it, pick the time signature, and choose how many bars to count.

KEYBOARD-FIRST DRILLING • A — restart the loop region • S — cue: hold to play from the top of the loop, release to snap straight back • D — push-to-play: hold to listen, release to pause, hold again to carry on

MOVE THE LOOP, KEEP ITS LENGTH Dial in the right length once, then walk it through the piece — the loop slides, its length stays put. • [ and ] nudge the loop back or forward by a second • Shift+[ and Shift+] step it by its own length — march through a passage one phrase at a time • Shift+drag a loop handle (on the timeline or in the zoom panel) to slide the whole loop; playback picks up at the new start

SAVED LOOPS Name and save loops per video — a save captures the loop region, the zoom, your practice marks, and your count-in, so a whole practice setup comes back in one tap. Rename a saved loop, or replace it with your current one. Come back tomorrow; your last loop is applied automatically.

SYNCED ACROSS YOUR DEVICES Saved loops follow you between computers through your browser's own account sync — set a loop at the desk, pick it up on the laptop. No Étude account and no server; when browser sync is off, loops simply stay local.

FREE. NO ACCOUNT. NO TRACKING. Étude collects no data — declared in the extension manifest, enforced by the only permission it asks for (storage, for your saved loops). Loops live in your browser and ride its built-in account sync (Chrome / Firefox) across your devices — never through an Étude server. Uninstalling the extension removes the local copy.
