A sheet music app for string players who can't spare a hand

SheetScroll follows strings by ear and turns the page for you, two beats before the end of the page, never early. Your bow arm and your fingering hand stay on the instrument. It opens your PDF parts and scans exactly as printed. The reader and the violin and cello courses are free; listening is Pro.

What does a string player need from a music stand?

A string player uses both hands, all the time. The bow arm cannot stop, and the left hand is holding a position. A page turn comes in the middle of a long phrase, and there is no good place to lift.

In a quartet or an orchestra you also read parts, not scores. A part is a long line of notes, often with many bars of rest, and a turn hides in the middle of a page you cannot see ahead.

You also need the page to be a page: the printed edition, with the bowings and fingerings someone wrote in.

How does SheetScroll turn pages for strings?

SheetScroll listens through the microphone and follows strings, along with keyboards, woodwinds, brass, voice and guitar. It turns two beats before the end of the page, as your eyes reach for the next line. It does not scroll at a set speed, so a held note or a slower tempo does not rush you.

A recording of the Prelude from Bach’s Cello Suite No. 1, followed in half-page view with nothing scripted: the next page’s top half arrives while the bottom half is played, then the rest of the page. Sound: an excerpt of “Cello Suite – Bach” by Lud and Schlatts Musical Emporium, conducted by Philip Milman, CC BY 3.0. Score: PDMX, CC0.
  • Your own parts: open a PDF, or photograph a paper part. SheetScroll shows it exactly as it looks on paper.
  • Half-page turns: the next line shows before the last one is done, so no bar is hidden.
  • Never early: if a theme comes back with a different ending, it holds the page and outlines the bars it is choosing between. Play on, or tap the bar.
  • Repeats and jumps: repeat signs, first and second endings, D.S. and coda are followed.

Can I keep my bowings and fingerings?

Yes. Write on the music with the pencil, highlighter, fingerings and symbols. Each mark stays with its bar in every view.

Marks on a part are free, and so is every view.

What is the best setup for violin, viola or cello?

  • Tablet size: a 10-inch or larger tablet shows a full page at a size a violinist can read at arm's length. A smaller one works in half-page view.
  • Mounting: a tablet clamped to a music stand is steadier than one leaning on the stand's tray. For a cello, set the stand so the screen is level with your eyes, not your bow.
  • Pedals: a Bluetooth page-turn pedal is a natural fit for a seated cellist. It works alongside listening, and a press always wins.
  • Sound: place the device where it hears you, not behind the stand's lip. Test in the room you will play in.
  1. Open the part.
  2. Play. The page turns two beats before its end.
  3. If a turn is early or late, tap the page and choose Report a turn. The report holds what SheetScroll decided, never audio.

Is there a course for violin or cello?

Yes. Free violin and cello courses are built in, with public-domain pieces in teaching order, from the first notes. They listen and turn without Pro, so a beginner can try the whole idea before paying anything.

What is free, and what is Pro for string players?

The reader is free forever: every format and view, annotations, setlists, and turns by pedal or tap. Pro adds listening to your own parts and automatic turns: $5.99 a month, $29.99 a year with 2 weeks free, or $79.99 once.

Questions

Can SheetScroll hear a violin or a cello?

It follows strings through the microphone, along with piano, woodwinds, brass, voice and guitar.

Will it turn the page too early in a part with repeated figures?

It turns only when it is sure where you are. When two passages sound alike it holds the page, outlines the places it is choosing between, and waits for the music to tell them apart.

Can I use my own orchestra parts?

Yes. Open a PDF or scan the paper part. SheetScroll shows it exactly as printed and keeps your markings with their bars.

What if I use a pedal as well?

Pair a Bluetooth page-turn pedal. It works alongside listening, and each press tells SheetScroll where you are.

Does it work in a rehearsal hall with no Wi-Fi?

Yes. Listening and reading run on the device, in airplane mode too.
