Grace Notes & Special Notation
Understand how Crescendo handles grace notes, tied notes, and other ornamental notation during practice mode.
Quick Overview
- ✓ Grace notes are required — You must play them before the main note to advance
- ✓ Tempo-aware timing — The app gives you more time at slower tempos, less at faster tempos
- ✓ Tied notes — Only the first note requires a key press; held notes are automatic
- ✓ Ornaments display — Trills, turns, and fermatas are shown but not checked
1 What Are Grace Notes?
Grace notes are small decorative notes that embellish a main (principal) note. They add expression and elegance to a melody. In sheet music, they appear as smaller notes connected to the main note.
Acciaccatura (Slashed)
A small note with a diagonal slash through the stem. From Italian meaning "to crush"—played very quickly, almost simultaneously with the main note.
The main note receives the emphasis; the grace note is fleeting.
Appoggiatura (Unslashed)
A small note without a slash. From Italian meaning "to lean upon"—played on the beat and given more time, often half the value of the main note.
The grace note receives emphasis; it's melodically important.
Musical context: Grace notes are especially common in Baroque (Bach), Classical (Mozart, Haydn), and Romantic (Chopin, Liszt) piano music. They add character and ornamentation to melodic lines.
2 How Crescendo Handles Grace Notes
When you encounter a position with grace notes, Crescendo uses a two-phase approach:
Phase 1: Play the Grace Notes
First, play all the grace notes. You don't need to hold them—just press and release each one. The app tracks that you've played them within a timing window.
Phase 2: Hold the Main Notes
After playing the grace notes, press and hold the main (principal) notes. The cursor advances once you're holding all required main notes.
Think of it as one gesture: Play the grace notes quickly, then land on and hold the main note. This mirrors how grace notes are performed musically—a single flowing motion into the destination note.
3 The Timing Window
Crescendo uses a tempo-aware timing window for grace notes. This means the app adjusts how much time you have based on your current tempo setting:
| Tempo | Timing Window | Feel |
|---|---|---|
| 60 BPM (slow) | ~700ms | Relaxed—plenty of time |
| 120 BPM (moderate) | ~350ms | Natural—comfortable pacing |
| 180 BPM (fast) | ~230ms | Quick—requires precision |
The window scales proportionally: slower tempos give you more time, faster tempos demand quicker execution. This matches real musical performance—grace notes at a slow tempo can be more deliberate, while at fast tempos they must be crisp.
If practicing at a slow tempo: You have more time, but don't play the grace notes too far apart from the main note. Aim for a connected gesture even when practicing slowly.
4 Tied Notes
A tie connects two notes of the same pitch, indicating they should be played as one continuous sound. Crescendo handles this intelligently:
First Note Only
Only the first note in a tie chain requires you to press the key. This is the "attack" note—where you initially strike the key.
Continuation Notes Skipped
Subsequent tied notes (continuations) are automatically skipped during note checking. The cursor moves past them without requiring any additional input.
Why this makes sense: When you play a tied note on a real piano, you strike the key once and hold it through the tie. Crescendo mirrors this—one keypress for the entire tied duration.
5 Other Special Notation
Crescendo displays various musical symbols but doesn't check all of them during practice. Here's what to expect:
Trills
(Displayed, not checked)
Trills appear in the score as written, but the app doesn't require you to execute the rapid alternation. Play the main note to advance.
Turns, Mordents, and Other Ornaments
(Displayed, not checked)
These decorative symbols appear in the notation but aren't validated during practice. Focus on learning the ornament patterns separately.
Fermatas
(Displayed, not enforced)
Fermata symbols (pause marks) appear but the app doesn't enforce extended holds. Practice mode continues at your pace.
Repeat Signs and Navigation Marks
(Displayed, used in playback)
Repeat bars, D.C., D.S., and coda markings appear in the score. In playback mode, repeats are followed; in practice mode, navigate manually using tap-to-jump or A-B loops.
Practice ornaments separately: While the app validates grace notes, other ornaments like trills require separate practice. Listen to recordings, learn the patterns, then apply them as you play.
6 Practice Tips for Grace Notes
Grace notes can feel tricky at first. Here are proven strategies for mastering them:
Play them as a single gesture
The most common mistake is playing grace notes too separately from the main note. Instead, think of the grace note and main note as one fluid motion—a quick "crush" into the destination.
Practice this by exaggerating the connection: play the grace note and immediately roll into the main note without any pause between them.
Start slow, then speed up
Use the tempo slider to practice grace note passages at a comfortable speed first. The tempo-scaled timing window gives you more leeway at slower speeds.
Once the gesture feels natural, gradually increase the tempo. Your fingers will develop muscle memory for the quick motion.
Use appropriate fingering
Choose fingering that allows a smooth, connected motion between the grace note and main note. Often this means using adjacent fingers (like 2-1 or 3-2).
See Fingering Annotations to mark your preferred fingering directly on the score.
Listen to performances
Hearing how professional pianists execute grace notes helps develop musical intuition. Notice how they're quick but not rushed, connected but not muddy.
The exact timing and emphasis can vary by era and style—Baroque grace notes differ from Romantic ones.
Isolate difficult passages
Use A-B loops to focus on sections with tricky grace notes. Repeat the passage until the gesture becomes automatic before moving on.
Troubleshooting
The cursor isn't advancing even though I played the grace note
Remember the two-phase approach: first play all grace notes, then hold the main notes. If there are multiple grace notes at a position, you need to play all of them within the timing window.
Also check that you're holding the main note after playing the grace notes—just pressing the main note briefly isn't enough.
The timing feels too tight at fast tempos
Reduce the tempo using the slider. At slower speeds, you get a wider timing window to play grace notes comfortably.
Once the motion feels natural at a slower tempo, gradually increase speed. This builds the muscle memory needed for faster execution.
I don't want to play the grace notes right now
Grace notes cannot be skipped—they're part of the musical notation and the app requires them for accurate practice. If a passage with grace notes is too challenging, use a slower tempo to give yourself more time, or use A-B loops to practice just that section repeatedly until it becomes comfortable.
A tied note is being skipped unexpectedly
This is expected behavior. When notes are tied, only the first note (the "attack") requires input. Subsequent tied notes are continuations and are automatically skipped. This matches how you'd actually play the passage on a piano—one keypress held through the tie.
