Chord timeline
See detected chords at the moment they happen, then move, replace or change the voicing.
GTR Player turns music you own into a clear, editable guitar practice timeline—with chords, notes, lyrics and the tools to make every song your own.
At launch: 10 imported songs free forever, with every feature and all edits saved. Plus 48 included backing tracks, separate from your imports. No timed trial.
Absolutely no ads ever.
This is a direct recording of GTR Player. Watch the timed lyrics, strings, chord diagrams and playhead move together.
Amazing Grace is a public-domain composition used here as a simple demonstration.
Start from the song—not a blank page. GTR Player keeps the recording and everything you add aligned on one visual timeline.
See detected chords at the moment they happen, then move, replace or change the voicing.
Add individual guitar notes, place them on a string and fret, and position them precisely in time.
Detect words from the recording, paste and time your own lyrics, or add a phrase manually. Review the draft in TIMELINE, then read saved lyrics above the chords in CHORDS. Compare the lyric tools.
Mark a verse, solo or tricky bar, then loop that section until it feels natural.
Adjust the audio pitch, change the displayed key and practise with familiar capo shapes.
Keep your GTR Player library available across your Mac, iPad and iPhone when you use the same iCloud account.
Move around the timeline, play at 0.5×, 0.75× or full speed, and return to important moments. Use ‹ Start beside Pentatonic in the top bar to return to the beginning.
Find a song by title, artist, genre or a chord it contains—not just by filename.
Use a bright light view or a focused dark view, with layouts designed for Mac, iPad and iPhone.
Start soloing with one movable pentatonic finger pattern. Explore root notes, the fretboard, major scales and chord notes with clear diagrams in Help on Mac and iPad.
Practise in all twelve keys with 48 included tracks: red scale backing tracks and green pentatonic backing tracks. Standard song posters use blue.
GTR Player gives you a head start, while keeping you in control of every musical detail.
Import a compatible audio file you own or are licensed to use.
WAV, MP3, M4A, AAC, AIFF, FLAC, ALAC and CAF, plus audio from compatible MP4, MOV and M4V files.
On-device analysis creates a chord timeline to begin with.
Correct a chord, choose another voicing, add notes, lyrics and regions.
Slow the song down, loop a part, change key or use capo shapes.
Chords and notes are most useful when you can see exactly where they belong in the music. GTR Player keeps every edit attached to the song’s timeline.
Amazing Grace was built and opened in GTR Player, then captured directly from the app. These are real app screens, not redrawn timelines.
Timed lyrics sit above six guitar strings, with real chord diagrams positioned along the song.
If you’ve added lyrics, they appear on one line above the chords. Exactly two complete rows stay on screen. Lyrics and chords each stay on one line, with fewer bars across crowded passages. Play the top row, then the bottom row. Half a second after the blue dot reaches the last chord, the next two rows appear. The dot waits above the rows until the next chord starts. Next shows the upcoming chord name, without a timer. On Mac, click a chord to hear it and double-click to edit. On iPad, tap a chord to hear it and double-tap to edit. These actions work in TIMELINE and CHORDS. The chord instructions stay at the top right in both views. The Pentatonic first-finger fret stays beside Views.
Amazing Grace is a public-domain composition. A modern recording or arrangement may still have separate rights. View the Library of Congress source.
The number beside Views is the starting fret for the movable pattern in Help → Guitar Theory.

In this screenshot, G major shows fret 12.
The same shape works for major and minor. Use the starting fret shown for your song’s key.
The display shows 12, so start playing the pentatonic pattern with your first finger at fret 12 on the low E string (the thickest string). Keep the same finger pattern and move the whole shape to that position.
For other keys, use the fret number shown: D major shows 7, C major shows 5, and C minor shows 8. The value is a starting fret, not a finger number. Follow the major or minor lesson that matches the displayed key.
The number follows the displayed key, including song key changes and changes made with KEY. A dash (—) means the key is hidden or unavailable. The guide does not change the audio or play notes for you.
Open Help → Guitar Theory to learn the pattern. The same guide is available in the app on Mac and iPad.
Use the Timeline to place and adjust lyrics. The CHORDS view gives you a clear reading layout above the chord diagrams.
Open Settings → + LYRICS. From CHORDS, the app automatically switches to TIMELINE for editing.
Automatic words and timings are approximate drafts. Phrases may be missed, words may be mistaken, and starts or ends can need adjustment. Existing lyrics are kept unless you choose Replace existing lyric regions. Save applies one undoable change; Cancel leaves saved lyrics untouched.
The included lyric model works offline, including first use. First-time on-device preparation can take several minutes. Audio and lyrics stay on your device.
Follow the complete lyrics and manual timing guide →
A phrase appears once across its saved range. If it crosses a row break, only the remaining words continue below. Lyrics never wrap within a row. Two complete chord rows stay visible, with a change to the next pair half a second after reaching its last chord. The display does not invent word-level timing.
Choose Settings → + NOTES → Delete all notes, then confirm. Cancel keeps the notes.
This clears every note in the song currently open. Chords, lyrics, practice regions and audio are kept. Use Undo to restore the notes. Delete Selected Notes removes only your selection.
Scan Song for Notes adds opening-riff suggestions. Settings → DETECT NOTES rebuilds the open song’s note suggestions after confirmation. Read the chord and note guide →
Give each song its own colour, with readable white lettering and an optional gradient on both Mac and iPad.
The circle beside Notes on a song poster is a marker you control. Tick it to remind yourself that this song has notes. Click on Mac or tap on iPad to tick or untick it. It does not add notes or change playback.
Explore the main areas of the app. Select a screen to enlarge it.
GTR Player is a focused practice tool. It helps you work with music you already have—it is not a music shop or streaming service.
Yes. Choose Settings → + LYRICS in CHORDS and GTR switches to TIMELINE. Detect words, paste and time lyrics, or add one phrase there. Selected-lyric actions and Delete all lyrics for this song have different scopes; whole-song deletion asks for confirmation and supports Undo. CHORDS displays the saved lyrics above the chord rows for reading. Compare the lyrics menu choices →
The lyric model is included and works offline, including first use. Audio and lyrics stay on your device. First-time preparation can take several minutes; repeat runs can be faster. The percentage shows audio processed, not accuracy or time remaining. Words and timings are approximate drafts: listen and adjust wording, starts and ends. No overall lyric-accuracy percentage is established.
Choose Settings → + NOTES → Delete all notes and confirm. It affects only notes in the open song; chords, lyrics, regions and audio are kept. Cancel keeps the notes, and Undo restores a completed deletion. Delete Selected Notes removes only selected notes.
It is your reminder that this song has notes. Click the circle on Mac or tap it on iPad to tick or untick it. The marker is set by you; it does not add notes or change playback. See the Notes reminder guide.
Yes. Press and hold a Library poster, choose Blue, Red, Green, Purple, Teal, Slate, Brown or Black, optionally turn Gradient on, and save with the checkmark. Automatic returns to the usual category gradient. See the colour editor.
Compatible audio formats include WAV, MP3, M4A, AAC, AIFF (.aif/.aiff), FLAC, Apple Lossless (ALAC, usually .m4a) and CAF. You can also import audio from MP4, MOV and M4V files that contain a compatible audio track.
GTR Player opens its own .gtr song projects. A song file must be downloaded, readable and encoded in a format supported by your Apple device. Protected Apple Music subscription tracks and streaming-only songs cannot be imported.
GTR Player includes 48 original practice tracks for Guitar Theory: major and minor scale guides plus musical backing tracks for pentatonic soloing, across all twelve keys. Import your own compatible songs to build your own personal song library. Commercial songs are not supplied.
It is the fret where your first finger starts the movable pentatonic pattern on the low E string. In the screenshot, 12 means start at fret 12. See the screenshot and examples.
The cleaner and clearer the song recording, the more accurate GTR Player’s chord detection is likely to be. Older recordings or poor-quality transfers from tape or CD may contain hiss, distortion and other artefacts that reduce accuracy. Use the detected chords as a helpful starting point, then correct any that need changing.
In our test of 742 song files, audio-only chord detection averaged around 80% agreement with supplied reference chords; the median song scored over 80%. These rounded figures measure reference agreement during stable chord passages, not the percentage of every chord correctly detected throughout a song. Results vary with the recording.
Song analysis takes place on your device. GTR Player stores its Library in your personal iCloud account when iCloud is available; otherwise it uses local device storage. You can also import downloaded song files from another cloud provider through Files or Finder. Automatic GTR Player Library sync between devices uses iCloud; another provider does not automatically sync the in-app Library. GTR Player does not upload your music to a developer music server.
Yes, when your devices use the same Apple Account and iCloud Drive is enabled for GTR Player. On iPad or iPhone, open Settings → your name → iCloud → Drive. On Mac, open System Settings → your name → iCloud → Drive. Turn on device syncing and allow GTR Player in the apps using iCloud Drive. See Apple’s iCloud Drive setup guide → Read the GTR Player Library sync guide →
Yes. You can edit and practise with songs already downloaded to your device. An internet connection is needed for iCloud to sync changes between devices.
Yes. You can change the chord name or choose another voicing of the same chord. For example, change from an F shape starting at fret 1 to another F shape starting at fret 8. If an F should be F7 throughout a song, edit it and choose Apply to All to change matching chords together. Chords, notes, lyrics and regions can also be moved and edited.
Note scanning looks for short, clear riffs and manageable melodies that you can practise on guitar. A useful phrase may come from guitar, piano, harmonica, synth or another pitched instrument. Settings → DETECT NOTES analyses the open song and rebuilds its note suggestions after confirmation. The separate + NOTES → Scan Song for Notes command checks the opening phrase and adds a clear riff if it finds one. Otherwise, that scan may offer a sparse chord-based practice pattern; that pattern is a suggestion, not a transcription of the recording.
Chord detection: around 80% agreement with reference chords in our 742-song test, measured during stable chord passages. Results vary with the song and recording quality. This figure applies to chords; we have not established a reliable overall note-detection accuracy percentage.
Fast solos, rapid runs, overlapping instruments and heavily distorted passages are harder to recognise reliably. Note detection is intended as a readable starting point for guitar practice, rather than a complete bass transcription. Listen to the recording, review the suggested notes and edit them to suit your playing.
No. It is designed to find simple riffs and place clear, playable notes on the timeline. A song may begin with an easy phrase and later move into a fast solo with overlapping notes. Rapid runs, heavy distortion and several instruments playing together are harder to separate, so notes may be missed or mistaken. Use the result as a starting point, then listen and make corrections.
We have not established a reliable overall note-detection accuracy percentage. More detected notes alone would not prove better recognition.
If a detected F chord should be F7, change that chord in the editor. Choose Apply to All to change matching F chords to F7 throughout the open song. Read the chord and note detection guide →
