Arpeggio Technique
Playing Broken Chords with Fluency and Control
Section titled “Playing Broken Chords with Fluency and Control”Technique Coach | Piano School Intermediate Course
Arpeggios are broken chords — the notes of a chord played one at a time rather than all together. They appear everywhere in piano music: Alberti bass accompaniments, sweeping classical passages, rolling pop ballad patterns, and jazz chord explorations. In the beginner course, you played basic broken chord patterns. This handout builds true arpeggio technique: 1-2 octave arpeggios with proper thumb-under crossing, multiple chord types, and musical accompaniment patterns.
Injury Prevention Warning: Arpeggio thumb crossings require a WIDER stretch than scale crossings because you skip notes. Never force the stretch. If your hand feels strained when crossing from finger 3 to the thumb across a wide interval, STOP. The stretch will develop naturally over weeks of gentle practice. Forcing it risks tendon strain.
1. How Arpeggios Differ from Scales
Section titled “1. How Arpeggios Differ from Scales”In a scale, the thumb crosses under to the NEXT adjacent note (e.g., E to F — one half step). In an arpeggio, the thumb crosses under to a note that is a 3rd or 4th AWAY (e.g., E to G, or E to A). This wider crossing demands:
- More horizontal wrist movement — the wrist shifts smoothly in the direction of travel
- Earlier thumb preparation — begin moving the thumb under as soon as possible
- Relaxed hand — tension makes wide crossings impossible
2. Major Arpeggio Fingerings
Section titled “2. Major Arpeggio Fingerings”Standard Fingering Pattern
Section titled “Standard Fingering Pattern”Most major and minor arpeggios use:
Some arpeggios starting on black keys use modified fingerings — these are noted below.
Exercise 1: C Major Arpeggio — 1 Octave (RH)
Section titled “Exercise 1: C Major Arpeggio — 1 Octave (RH)”Level: 1 | Tempo: 50 BPM | Hands: RH
Starting Position: RH thumb (1) on C4 (Middle C).
The Exercise:
Play one note per beat. Ascending then descending without stopping.
Repeat: 4 times.
What It Should Feel Like: The hand “opens up” as you ascend — each interval is wider than in a scale. The wrist guides the hand smoothly to the right. On the way down, the hand contracts gently back toward the starting position.
Common Mistakes:
- Jerky motion at the top (G to high C): How to fix — the shift from finger 3 to finger 5 is a hand position change, not a finger stretch. Let the wrist carry the hand to the new position.
- Accenting the thumb note (C) when crossing: How to fix — isolate G(3)-C(1) ascending and practice 10 times at 40 BPM. The thumb note should be softer than or equal to the G.
When to Move On: 3 smooth runs at 50 BPM with no accents and no hesitation.
Exercise 2: C Major Arpeggio — 1 Octave (LH)
Section titled “Exercise 2: C Major Arpeggio — 1 Octave (LH)”Level: 1 | Tempo: 50 BPM | Hands: LH
Starting Position: LH pinky (5) on C3.
The Exercise:
Repeat: 4 times.
What It Should Feel Like: The LH arpeggio feels slightly different from the RH because the weaker fingers (4, 5) start the pattern. Ensure finger 5 on C3 is firm but not tense.
Common Mistakes:
- Finger 5 too weak on the starting C: How to fix — press finger 5 with the same firmness as finger 1. You may need to engage the hand muscles slightly more.
- Collapsing finger joints: How to fix — every finger maintains its curved shape. Flat fingers lose control on wide intervals.
When to Move On: 3 smooth runs at 50 BPM.
Exercise 3: C Major Arpeggio — 2 Octaves (RH)
Section titled “Exercise 3: C Major Arpeggio — 2 Octaves (RH)”Level: 2 | Tempo: 60 BPM | Hands: RH
Starting Position: RH thumb (1) on C4.
The Exercise:
The thumb crosses under TWICE on the way up. Each crossing spans a 4th (G to C).
Repeat: 4 times.
What It Should Feel Like: The wrist floats slightly to the right on each ascending crossing, carrying the hand to the next octave. It should feel like a gentle wave motion — rise (cross), settle, rise (cross), settle, arrive.
Common Mistakes:
- Thumb arriving late on the second crossing: How to fix — begin preparing the thumb under as soon as finger 2 plays E. Do not wait for finger 3.
- Losing evenness between octaves: How to fix — the second octave often gets rushed. Metronome is essential.
When to Move On: 3 runs at 60 BPM with even tempo and tone across both octaves.
Exercise 4: All Major Arpeggios — 1 Octave
Section titled “Exercise 4: All Major Arpeggios — 1 Octave”Level: 2 | Tempo: 50 BPM | Hands: HS then HT
Starting Position: Each arpeggio starts on its tonic.
The Exercise:
Practice these 6 major arpeggios (the most common keys in intermediate repertoire):
| Key | Notes | RH Fingering | LH Fingering |
|---|---|---|---|
| C Major | C-E-G-C | 1-2-3-5 | 5-3-2-1 |
| G Major | G-B-D-G | 1-2-3-5 | 5-3-2-1 |
| D Major | D-F#-A-D | 1-2-3-5 | 5-3-2-1 |
| F Major | F-A-C-F | 1-2-3-5 | 5-3-2-1 |
| A Major | A-C#-E-A | 1-2-3-5 | 5-3-2-1 |
| E Major | E-G#-B-E | 1-2-3-5 | 5-3-2-1 |
Learn one arpeggio per practice session. RH alone, then LH alone, then hands together (one octave apart, playing the same chord tones).
Repeat: 4 times per hand, per arpeggio.
What It Should Feel Like: Each arpeggio has its own “hand shape” — the pattern of black and white keys under your fingers is unique. D major (with F#) and A major (with C#) feel noticeably different from C major.
Common Mistakes:
- Using scale fingering instead of arpeggio fingering: How to fix — arpeggios skip notes, so fingerings are different. Do not carry scale habits into arpeggios.
When to Move On: All 6 arpeggios played smoothly at 50 BPM, hands separately.
3. Minor Arpeggios
Section titled “3. Minor Arpeggios”Exercise 5: Minor Arpeggios — 1 Octave
Section titled “Exercise 5: Minor Arpeggios — 1 Octave”Level: 2 | Tempo: 50 BPM | Hands: HS then HT
Starting Position: Each arpeggio starts on its tonic.
| Key | Notes | RH Fingering | LH Fingering |
|---|---|---|---|
| Am | A-C-E-A | 1-2-3-5 | 5-3-2-1 |
| Em | E-G-B-E | 1-2-3-5 | 5-3-2-1 |
| Dm | D-F-A-D | 1-2-3-5 | 5-3-2-1 |
Follow the same practice protocol as Exercise 4.
What It Should Feel Like: Minor arpeggios feel “narrower” in the first interval (minor 3rd = 3 half steps) compared to major arpeggios (major 3rd = 4 half steps). Your hand position is slightly more compact at the start.
Common Mistakes:
- Playing the major 3rd by habit (e.g., C# instead of C in Am): How to fix — sing or say the notes before playing. Know what you are going to play before your fingers move.
When to Move On: All 3 minor arpeggios at 50 BPM, hands separately, correct notes.
4. Broken Chord Patterns
Section titled “4. Broken Chord Patterns”Arpeggios in real music rarely appear as simple ascending/descending runs. They appear as patterns. These three patterns are the most common in intermediate repertoire.
Exercise 6: Alberti Bass Pattern
Section titled “Exercise 6: Alberti Bass Pattern”Level: 1 | Tempo: 60 BPM | Hands: LH
The Exercise:
Play in eighth notes (2 notes per beat at 60 BPM). This is the classic Alberti bass pattern: bottom-top-middle-top.
Apply the same pattern to these chords:
- F major: F(5) C(1) A(3) C(1)
- G major: G(5) D(1) B(3) D(1)
- Am: A(5) E(1) C(3) E(1)
Repeat: 4 bars per chord, then cycle through all 4 chords without stopping.
What It Should Feel Like: A rocking, wavelike motion. The fingers stay close to the keys and “roll” through the pattern rather than lifting high. The wrist remains still — only the fingers move.
Common Mistakes:
- Lifting fingers too high between notes: How to fix — hover no more than 1 cm above the keys. The Alberti bass should be smooth and quiet, not percussive.
- Accenting the bottom note: How to fix — all 4 notes in the pattern should be equal volume. The pattern provides rhythm, not melody.
When to Move On: All 4 chords played in sequence, 4 bars each, at 60 BPM with smooth, even tone.
Exercise 7: Arpeggiated Accompaniment
Section titled “Exercise 7: Arpeggiated Accompaniment”Level: 2 | Tempo: 50 BPM | Hands: LH
Starting Position: LH spanning C3 to G3.
The Exercise:
Pattern (one bar in 4/4): C(5) E(3) G(1) E(3) | (ascending-descending wave)
Play in eighth notes. This pattern sweeps up and down through the chord, creating a flowing accompaniment (think: ballad-style piano).
Apply to: C major, Am, F major, G major (a I-vi-IV-V progression).
Repeat: 4 bars per chord in sequence, cycling through the progression.
What It Should Feel Like: Like gently strumming a guitar — a continuous wave of sound that supports a melody. The motion is smooth and connected (legato).
Common Mistakes:
- Gaps between notes: How to fix — hold each note until the next one sounds. The notes should overlap very slightly for a connected feel.
When to Move On: The 4-chord progression played continuously for 2 complete cycles with no gaps.
Exercise 8: Rolled Chords
Section titled “Exercise 8: Rolled Chords”Level: 2 | Tempo: 40 BPM | Hands: RH then LH
Starting Position: RH on C4-E-G (C major chord). LH on C3-E-G.
The Exercise:
Instead of playing all 3 notes simultaneously, “roll” them from bottom to top in rapid succession:
The entire roll happens within ONE beat. The final note (top) lands exactly on the beat. The lower notes lead into it.
Practice with: C major, F major, G major, Am chords.
Repeat: 4 times per chord.
What It Should Feel Like: Like a gentle wave sweeping upward. The fingers fall in sequence, not simultaneously. Think of dropping a hand flat onto a table — the fingers hit at slightly different times. That natural timing IS a rolled chord.
Common Mistakes:
- Rolling too slowly (each note clearly separated): How to fix — the roll should be very fast, almost like a simultaneous chord but with a subtle “spread.” Listen to harp music for the ideal sound.
- Releasing lower notes before upper notes sound: How to fix — ALL notes remain held after being struck. The rolled chord sustains as a full chord.
When to Move On: Rolled chords sound like one “spread” event, not three separate notes.
5. Seventh Chord Arpeggios
Section titled “5. Seventh Chord Arpeggios”Once you have learned 7th chords in theory (see music theory handout 03), practice their arpeggios.
Exercise 9: Seventh Chord Arpeggios
Section titled “Exercise 9: Seventh Chord Arpeggios”Level: 3 | Tempo: 50 BPM | Hands: RH then LH
Starting Position: Start on each chord’s root.
The Exercise:
| Chord | Notes | RH Fingering | LH Fingering |
|---|---|---|---|
| Cmaj7 | C-E-G-B-C | 1-2-3-4-5 | 5-4-3-2-1 |
| G7 | G-B-D-F-G | 1-2-3-4-5 | 5-4-3-2-1 |
| Am7 | A-C-E-G-A | 1-2-3-4-5 | 5-4-3-2-1 |
Play ascending (root to octave) and descending. One note per beat.
Repeat: 4 times per chord, per hand.
What It Should Feel Like: Seventh chord arpeggios span a wider range than triad arpeggios — you play 4 different notes before reaching the octave. The hand stretches slightly more, and the fingering uses all 5 fingers in a single octave.
Common Mistakes:
- Confusing B and Bb in G7 vs Cmaj7: How to fix — G7 uses B natural (the 3rd of G), then F natural (the b7). Cmaj7 uses B natural as the 7th. Know the chord BEFORE playing the arpeggio.
- Rushing because of the wider span: How to fix — metronome at 50 BPM. Every note gets a full beat.
When to Move On: All 3 seventh-chord arpeggios played smoothly at 50 BPM, each hand.
Safety Note: Seventh chord arpeggios demand more hand stretching than triads. If your hand feels tight after 5 minutes, stop and do the hand stretches from your daily warm-up (see handout 07).
6. Speed Building for Arpeggios
Section titled “6. Speed Building for Arpeggios”Exercise 10: Arpeggio Speed Protocol
Section titled “Exercise 10: Arpeggio Speed Protocol”Level: 3 | Tempo: 50 BPM building to 80 BPM | Hands: RH then Both
Starting Position: 2-octave C major arpeggio.
The Exercise:
Apply the same speed protocol from technique handout 01 (Advanced Scale Technique, Exercise 11):
- Play 3 perfect repetitions at 50 BPM.
- Increase by 5 BPM.
- If any mistake, drop back 5 BPM.
- Target: 70 BPM (Level 2), 80 BPM (Level 3).
Repeat: 10 minutes maximum per practice session for arpeggio speed work.
What It Should Feel Like: The wrist guides the hand more actively at higher tempos. The thumb crossings become a continuous flowing motion rather than discrete events. The sound should be a smooth waterfall of notes.
Common Mistakes:
- Finger tension at higher speeds: How to fix — if your fingers feel tight, you are gripping the keys. Release. Play softer. The faster you play, the lighter your touch should be.
- Uneven note spacing: How to fix — record yourself with the CT-X9000IN’s MIDI recorder and listen for gaps or rushes in the playback.
When to Move On: 2-octave C major arpeggio at 70 BPM with connected, even tone = Level 2. At 80 BPM = Level 3.
Safety Note: Speed work on arpeggios is more physically demanding than on scales because of the wider stretches. Warm up thoroughly (handout 07) before speed work. Stop if any discomfort in the thumb web (the fleshy area between thumb and index finger).
