Scan Sheet Music Correctly – Why “Structure First” Is Essential

You’ve successfully scanned your sheet music—but when you start editing, things suddenly don’t make sense:

rhythms don’t match
voices are mixed up
export results are broken

👉 The reason is almost always the same:

You started fixing details instead of fixing the structure.

ScanScore follows a fundamental rule:

👉 Structure First, Details Second

Ignoring this rule will inevitably lead to errors—no matter how good your scan is.

🧠 Why “Structure First” Is So Important

After scanning, ScanScore often shows:

blue error markings
incorrectly grouped systems
misassigned instruments

This is completely normal.

👉 What matters is how you handle it.

Many users make this mistake:
➡️ They immediately start correcting notes, dynamics, or text

The problem:
👉 The underlying structure is still unstable

According to the guide:

👉 If the structure is wrong, all further corrections become unreliable

⚠️ The Biggest Mistake After Scanning

Right after scanning, you’ll notice many small issues:

incorrect notes
misplaced dynamics
wrong articulations

👉 This tempts you to fix them immediately.

But:

❌ Editing notes too early
❌ Adjusting text prematurely
❌ Moving voices around

➡️ will create even more problems

Why?

👉 Because all of these depend on the structure.

🧩 The “Structure First” Rule Explained

ScanScore recommends a strict order for editing.

👉 Always start with:

Fix systems
Assign instruments
Link staves across systems (Staff IDs)
Check staff groupings (brackets, braces)
Correct key signatures
Correct time signatures
Fix measure bars and repeats

Only after that:

👉 Move on to details

🔧 Step 1: Fix Systems

Common problems:

systems merged incorrectly
systems split incorrectly
staves assigned to wrong lines

👉 Solution:
Use the System Editor

Goal:

each system contains the correct staves
no mixing between systems

🎻 Step 2: Assign Instruments Correctly

After scanning, instruments are often:

mislabeled
not recognized properly

👉 This leads to:

wrong playback sounds
incorrect MusicXML export

👉 Solution:
Use Change Instruments

🔗 Step 3: Link Staves Across Systems

In larger scores:

instruments disappear and reappear

👉 Without proper linking:

ScanScore treats them as different instruments

👉 Solution:
Use System Manager / Staff IDs

Goal:

each instrument remains consistent across the entire score

🎼 Step 4: Check Staff Groupings

Typical issues:

missing brackets
incorrect grouping (e.g. piano grand staff)

👉 Important for:

visual structure
MusicXML export

🎹 Step 5: Correct Key Signatures

If the key is wrong:

accidentals become incorrect
notes appear “wrong”

👉 Always fix the key signature first before editing notes

⏱️ Step 6: Correct Time Signatures

Incorrect time signatures lead to:

blue error markings
broken rhythms

👉 Important rule:
Fix time signatures before correcting rhythm

🔁 Step 7: Fix Measure Bars & Repeats

Common issues:

missing barlines
merged measures
incorrect repeats

👉 These affect:

playback
export
overall structure

🚫 What Happens If You Ignore Structure?

If you start with details too early:

errors keep reappearing
export results break
rhythms stay incorrect
voices collapse

👉 Result:
more work, worse outcome

🧭 The Correct Workflow (Simple Overview)

Phase 1: Scan

→ analyze the result

Phase 2: Fix structure

→ systems, instruments, measures

Phase 3: Fix details

→ notes, dynamics, text

🧠 Pro Tips

deliberately ignore details at the beginning
always work from “big to small”
review the entire score first
use playback only after structure is fixed

✅ Conclusion

The quality of your scan is not determined by the scan itself—
👉 but by how you process it afterward.
