Include your device, operating system, browser or app version, the score format and the steps that caused the issue. If a score fails to open, a small example file can help reproduce it.

Microphone access is blocked

In a browser, allow Microphone in this site’s permission settings. On mobile, also check the browser’s microphone permission in device settings. In the installed app, find Violin Spark in device settings and enable Microphone access. Open Tuner and try again.

Microphone detection requires a secure website connection (HTTPS) or a local development address. If another app is using your microphone, close it and try again.

Read note by note

Use the arrows to move through the score. Microphone practice and games are unavailable in this version.

A sound will not load

Open Tone, or Settings > Audio if the shortcut is hidden. Choose Retry for the failed sound. If Clear & retry is offered, it repairs the sample cache while keeping your scores and settings. You can also choose another sound.

The installed app includes its sounds for offline playback. On the website, a connection is needed to load sounds that are not already cached.

A score will not open

Violin Spark supports MusicXML (.musicxml or .xml), compressed MusicXML (.mxl), MIDI (.mid or .midi), and the Violin Spark score Markdown format (.md). General Markdown documents and scanned sheet-music images are not score formats.

For MIDI, choose a melody in the track picker to read the score. Files with multiple playable tracks also offer Play all beside the picker, including drums and tempo changes. Choose a melody track again to return to score reading.

Fingering guides look different from my teacher’s

Automatic fingerings use standard G–D–A–E tuning. They prefer first position in G3–B5 and suggest higher positions up to G7. Roman numerals mark position changes. Written fingerings take priority; adapt suggestions to the phrase. The fingerboard diagram shows first position only.

Your teacher may choose different strings or positions. Hide Fingers if you prefer to follow the original notation.
