Sheets: Exercises, Transcriptions & Teaching Materials
NewThis is an early release! If you spot anything odd or have feature requests, please let us know!
Sheets are now a full-featured workspace for your musical documents. Create exercises and drills with the notation editor, transcribe solos and melodies, or build teaching materials with rich text instructions and embedded notation.
Attach a YouTube video or upload audio to practice alongside your sheet, add PDF scans for reference, tag and organize by instrument, key, and difficulty, and share publicly for other musicians to discover, comment on, and practice with.
Link a sheet to any video in your library and it appears on the video's page for quick access.
Interactive Notation Editor
NewThis is an early release! If you spot anything odd or have feature requests, please let us know!
A brand new notation editor built from the ground up. Write music directly in the browser with point-and-click note entry, keyboard shortcuts, and a full toolbar for durations, accidentals, rests, ties, slurs, tuplets, and chords.
I built this as a kind of work of love which is a custom renderer and editor tailored to the needs of musicians who hate the clunkiness of traditional notation software.
Supports treble and bass clef (coming soon)/grand staff (coming soon), tablature for mandolin, guitar, bass, banjo, and violin, and professional engraving features including grace notes, dynamics, hairpins, articulations, fingerings, lyrics, tempo markings, key and time signature changes, repeat signs, volta brackets, navigation marks (D.S. al Coda, D.C. al Fine), rehearsal marks, and 8va/8vb lines.
Built-in playback lets you hear what you've written. Mobile-friendly with touch support for note entry and editing on the go. Your work saves automatically as you go.
Course Notation Upgraded
ImprovementAll notation examples in courses now use the new custom renderer with higher quality engraving, playback, and tablature support. Stay tuned — this opens the door for some exciting interactive course content coming soon!

Practice Tools in Navigation
ImprovementPractice Tools now has its own link in the header for quick access to courses, the metronome, and more. Look soon for more practice tools too! ;)
Courses
NewCourses are now available in Practice Tools. The first course, Basic Music Theory, covers notes, scales, rhythm, intervals, chords, progressions, arpeggios, and more with interactive notation and tablature. More courses are on the way — we're looking to collaborate with musicians on specialized topics. Feedback is welcome!

Leaderboard & Practice Log Enhancements
ImprovementLeaderboards now show all ranked users with pagination, compact icon tabs, and remembered selections. An interactive rank history chart shows your progress over time with click-to-practice-log. Calendar days without practice are now clickable for adding notes, with corner indicators and hover tooltips for days with notes.

YouTube Playlist Import
NewImport entire YouTube playlists by pasting a playlist URL on the playlists page. Sync anytime to pull in new videos that were added to the YouTube playlist. You can also mix in your own videos from your library — imported playlists are fully editable just like any other playlist. I also added new searching and sorting options for ease of use with large playlists.

View Counts
ImprovementShared videos and playlists now show how many times they've been viewed.
Video File Uploads
NewUpload video files alongside audio files. Want to slow down your lesson recordings? Recorded a cool solo at a concert? Slow Down's got you covered. Videos play inline with full speed, pitch, and vocal controls. Pitch shifting and vocal reduce/enhance use a server-extracted audio track for clean processing at any speed.
Cents Fine-Tuning on Uploads
ImprovementFine-tune pitch in 10-cent increments for uploaded audio and video files. Perfect for matching tracks that are slightly out of standard tuning.

Vocal Reducer
NewReduce or enhance vocals in real time using a machine learning model that runs entirely in your browser. A neural network listens to the audio stream, builds a spectral profile of the vocal frequencies, and applies it on the fly — no server round-trip required. Slide toward Reduce to push vocals into the background, or toward Enhance to bring them forward. Works with both YouTube videos and uploaded audio. Requires the Slow Down browser extension v1.1.0 or later (should update automatically, or grab the latest from the Chrome Web Store).
Key Detection
NewSlow Down now detects the musical key of your videos automatically. Audio is captured by the browser extension, encoded, and analyzed server-side to determine the key. The detected key is displayed in the song info panel. Still in beta — results are generally accurate but may occasionally miss, especially with short clips or complex harmony. I'll keep refining it. Requires the Slow Down browser extension v1.1.0 or later (should update automatically, or grab the latest from the Chrome Web Store).
BPM Detection
NewAutomatic BPM detection for your videos. Like key detection, audio is captured by the extension and analyzed server-side. The detected BPM is displayed in the song info panel and stays synced with the speed controls — when you slow a track down to 75%, the BPM display updates to show the effective tempo so you always know exactly how fast you're practicing. Still in beta — accuracy is good for most tracks but may be off for very slow, very fast, or rhythmically complex pieces. Requires the Slow Down browser extension v1.1.0 or later (should update automatically, or grab the latest from the Chrome Web Store).

Practice Tools
NewNew dedicated Practice Tools area — a growing collection of tools to level up your practice sessions. Access it anytime from the dashboard. It's also available in the video player as a compact remote control.
Metronome
NewA full-featured metronome with tap tempo, time signatures (2/4, 3/4, 4/4, 5/4, 6/8, 7/8, and custom), subdivisions (quarter, eighth, triplet, sixteenth), multiple click sounds (classic, mechanical, woodblock, rimshot), swing control, accent/ghost/mute per beat, random mute for independence training, and a gradual tempo trainer that automatically increases BPM over time. Available standalone or as a compact remote control inside any video.
