How to write on sheet music: pencil rules, app tools and the best annotation apps

Writing on sheet music now means two things: pencil marks on a printed part, and pen, highlighter, text and stamp tools in a tablet app. The habits carry over from one to the other. This guide covers the markings players add, the rules libraries expect on paper, how to annotate in an app step by step, and which app has the best annotation tools in our scores as of October 2026.

What do musicians write on sheet music?

Mostly reminders that save rehearsal time: how to play a passage, where to breathe, what to skip and when to look up. The usual markings:

• Fingerings: small numbers by the note, only where the fingering isn’t obvious. In the Henle Library app you can also switch printed artist fingerings on or off.
• Bowings: down-bow and up-bow signs, slurs and hooked bows. In an orchestra the concertmaster and section leaders usually decide them, and the library copies them into every part.
• Breath marks: a comma or check mark where a wind player or singer breathes.
• Dynamics and articulation: changes the conductor asks for, or printed marks you keep missing.
• Cuts: a note such as “Go to p. 7” where the cut starts.
• Cues: a few notes of another part before a long rest ends, so you know when to come in.
• Eyeglasses: a small pair of glasses drawn above a passage as a warning, for a tempo change, an exposed entry or a beat to watch.
• Navigation: counts in long rests, rehearsal letters you need to find fast and reminders before a quick page turn.

What are the rules for marking paper parts?

Use a soft pencil, mark lightly, and erase what only mattered to you before the part goes back. Edinburgh Music Library’s care notes for borrowed sets (revised February 2026) ask for a soft pencil, ideally B or 2B, and never ink or highlighter, and they ask groups to remove their pencil marks before returning a set.

The same notes say not to score out whole pages for a cut: write “Go to p. X” in soft pencil instead. Sticky tape, staples and folded corners also damage pages, and sets returned in poor condition can be sent back for cleaning or charged for.

Orchestras work the same way. The Tonhalle-Orchester Zürich describes its librarians copying bowings, dynamics and articulation from the first desks into the tutti parts in a soft pencil that can be erased when something changes in rehearsal. Even on music you own, light pencil lets you change a fingering next season without a smudge.

How do you annotate sheet music in an app?

Open the score, switch to annotation mode, pick a tool and write. The app stores your marks on top of the PDF, so the original stays clean. The steps follow forScore’s user guide, and other readers work the same way.

1. Enter annotation mode. In forScore, choose Annotate from the tools menu or touch and hold the page. With an Apple Pencil you can set it to start drawing as soon as the tip touches the screen.
2. Pick a pen or highlighter. Save the colors and widths you use as presets: forScore allows unlimited custom presets, Piascore has six configurable pens, and Henle Library offers four widths from thin to marker.
3. Add text. Text boxes hold words such as “listen to oboe”. forScore and Enote also accept Apple Pencil handwriting through Scribble, which turns it into typed text.
4. Use stamps for standard symbols. Stamps place clean dynamics, accidentals, fingerings or bow marks. forScore includes stamps and lets you make your own (forScore Pro adds almost 400 more), MobileSheets has hundreds plus custom stamps, Piascore has stamps for dynamics, fingerings and accidentals, and nkoda sorts its symbols into 27 categories.
5. Draw shapes. Slurs and hairpins look better as shapes than freehand. forScore has dynamic shapes, MobileSheets a crescendo tool, Newzik a Shapes tool (added in February 2026) and nkoda scalable slurs and hairpins.
6. Put markings on layers. A layer keeps one set of marks apart from the rest. forScore layers can be hidden or shown for all pages at once, MobileSheets lets you choose which layers are visible, and Newzik hides a layer with the eye icon next to its name.
7. Fix mistakes. Undo and redo cover your last strokes, the eraser removes single marks, and a selection tool moves or copies a group. forScore’s offers Move, Duplicate, Copy, Cut, Adjust and Clear.
8. Export an annotated PDF. To send your markings to someone who uses another app, export a PDF with the annotations drawn in. forScore and MobileSheets do this, Enote prints or exports with or without annotations, and Piascore needs its $5.99 Full Upgrade to export.

Should you annotate with a stylus or your finger?

A stylus is more precise for small numbers and accidentals, but a finger works too. forScore lets you draw with a finger or an Apple Pencil, and SongbookPro accepts a stylus, Apple Pencil or finger.

If you use a stylus, turn on a pencil-only setting so your fingers can turn pages and scroll without leaving stray lines. forScore calls it Prevent finger drawing, and Piascore added an Apple Pencil-only option in version 7.0.6. MobileSheets supports stylus pressure and lets you assign tool shortcuts to a stylus button, which helps on Android tablets that come with a pen.

Apple Pencil Pro adds a squeeze gesture that some readers use: MobileSheets added squeeze actions to its annotation editor in version 3.9.45, and forScore Pro adds Apple Pencil hover and squeeze gestures. Which pencil works with which tablet is covered in our guide to the best iPad for sheet music.

Which app has the best annotation tools?

forScore has the best annotation tools in our scoring, 9.5 out of 10, ahead of MobileSheets and Newzik at 9. Our annotation criterion rewards pens, highlighters, text and symbols, layers you can hide or share, stylus precision and easy editing, as set out in how we rank.

App	Annotation score	Tools, from our app profiles
forScore	9.5	Pen presets, layers, stamps, dynamic shapes, ruler, text, selection tool
MobileSheets	9	Pen, highlighter, text, shapes, arrows, crescendo and piano-staff tools, hundreds of stamps, layers, stylus pressure
Newzik	9	Pens, highlighters, shapes, symbols, text, pictures, private, public or shared layers
Enote	8	Pen, highlighter, shapes, bar-line and straight-line tools, text, lasso, layers
Piascore	7.5	Six pens, stamps, text boxes, shapes, without advanced layers
unrealBook	7.5	Colored pens and highlighters, text notes, hot spots
nkoda	7	Pens, highlighters, text, lasso, symbols in 27 categories, unlimited layers
Henle Library	7	Four pen widths, text, symbols in Henle’s music font, named layers
Planning Center Music Stand	7	Pen, highlighter, text, eraser, shared with the team
BandHelper	7	Pen, highlighter, sticky notes, white-out, shared or personal
OnSong	6.5	Pen, highlighter, layers, sticky notes, text (Premium only)
SongbookPro	6.5	Freehand in 20 colors, highlighter, typed notes

Musicnotes and Tomplay score 6 for annotation. MuseScore and Sheet Music Direct have no annotation tools, Soundslice has no pen or highlighter, and PlayScore 2 has a freehand pen on iPad only.

forScore’s lead comes from the depth of its tools and its Apple Pencil precision, but it runs only on Apple devices. MobileSheets matches most of that toolset on Android, Windows and iPad for a one-time price, though its developer lists an update to the annotation editor as still to come. Newzik covers the same kinds of tools, and our profile notes that some reviewers find them less fluid than forScore’s; where it pulls ahead is sharing layers with other players.

Our profile data for the four main PDF readers:

How do you share markings with a section or ensemble?

Newzik and Planning Center Music Stand share markings between players’ accounts, while MobileSheets and forScore share them through linked tablets or files. The right one depends on how your group already works.

• Newzik: in a Project, each member’s markings sit on a layer that can be private (only you), public (everyone sees it, only you edit it) or shared (everyone can see and edit it). Parts and layers sync in real time, so a principal’s bowings reach the section’s iPads before rehearsal. Essentials, a $24.99 one-time purchase, includes one Project, and unlimited Projects need Premium. Skip it if your section reads on Android or Windows tablets (only Newzik Web in a browser) or needs linked page turns, which Newzik dropped in 2021.
• Planning Center Music Stand: musicians open a teammate’s annotations, such as the worship leader’s, then merge them with their own or replace their own. You can also import your notes from another key of the same arrangement. Marks made offline reach others only after they sync, and Music Stand works only inside a church’s Planning Center Services account.
• MobileSheets: since version 3.9.35 (March 2026), annotations sync between tablets linked with Connect Tablets, with a choice of layers, across Android, Windows and Apple devices. Otherwise you share songs as .msf packages or as PDFs with the annotations embedded.
• forScore: send a score as a 4SC file, which keeps annotations editable for another forScore user, or as an annotated PDF for anyone else. There is no shared library or account-based sync between players.
• Others: BandHelper keeps shared and personal annotations for everyone in a band account. nkoda and Enote share annotation layers with other users of the same app (Enote recipients get static copies), and Henle Library sends layers to someone who owns the same Henle edition.

Which annotation app should you choose?

Choose by platform first, then by whether your markings stay with you or go to a group.

• Solo on iPad or Mac: forScore, the highest annotation score, for a one-time $24.99.
• Android, Windows or a band with mixed devices: MobileSheets, with layers, stamps and stylus pressure on every platform it supports. See forScore vs MobileSheets.
• Sharing markings with a section: Newzik, whose shared layers earn our highest collaboration score (9.5 out of 10).
• Church teams on Planning Center: Music Stand, to bring in the leader’s markings.
• No budget: Piascore annotates for free on iPad and iPhone. More options in our free sheet music apps.
• Catalog scores: nkoda has symbol toolboxes for each instrument family and shareable layers.
