C minor arpeggio

Notes of the C minor arpeggio

An arpeggio breaks a chord into single notes. The C minor arpeggio is the tonic triad plus the octave: C, E♭, G, C. The black key in the chord is E♭. The other chord tones are white keys.

C minor has three flats in the signature (B flat, E flat, A flat) and only one of them is in the arpeggio: E flat, the minor third. C, E flat, G, C. The right hand starts with the thumb on C and plays E flat with finger 2. The left hand uses 5 3 2 1 so finger 3 takes E flat. Do not add B flat or A flat. Those flats are in the key, not in this chord.

The C minor key signature is 3 flats: B♭, E♭ and A♭. Only the accidentals that are actually chord tones show up in the arpeggio. The others stay in the signature for the rest of the music in this key.

Fingering for both hands

Right hand, one octave up from C: 1 2 3 5. There is no thumb crossing inside that octave, because the fingers are 1, 2, 3 and 5. The crossing appears when you continue: the two-octave right hand is 1 2 3 1 2 3 5, so the thumb passes under finger 3 as you leave the fifth (G) and play the octave C.

Left hand, one octave up from C3: 5 3 2 1. Coming down, reverse the numbers in each hand. Fingers are numbered 1 (thumb) to 5 (little finger) in both hands.

Clef uses this right-hand pattern in its arpeggio drills: 1 2 3 5 for one octave, and 1 2 3 1 2 3 5 for two octaves, with the thumb crossing under after finger 3. The thumb lands on the root, which is a white key in every arpeggio on this page.

Inversions

The same three notes can start on a different chord tone. Root position is C, E♭, G. First inversion starts on the third: E♭, G, C. Second inversion starts on the fifth: G, C, E♭. The arpeggio above is root position. The inversions use the same keys and the same spelling.

Reading it on the staff

On the treble staff, C4 to C5 needs 1 ledger line below the staff. On the bass staff, C3 to C4 needs 1 ledger line above the staff.

Say the staff positions before you play. C4 sits on ledger line 1 below the staff of the treble staff. E♭4 sits on the first line from the bottom of the treble staff. G4 sits on the second line from the bottom of the treble staff. C5 sits in the third space from the bottom of the treble staff.

The reading trap is the signature. B♭, E♭ and A♭ are already in force, but you only play them when that letter is actually in the arpeggio. Name the chord tones out loud once, then play.

How to practise the C minor arpeggio

1. Say the notes, then the fingers: C, E♭, G, C, right hand 1 2 3 5.
2. Play the right hand alone at 60 beats per minute, one note per beat, and hold the shape so the hand does not collapse between notes.
3. Play the left hand alone with 5 3 2 1. Keep the thumb on C, which is a white key.
4. Stop on E♭ and check that the longer finger, not the thumb, is on the black key.
5. Add the two-octave right hand (1 2 3 1 2 3 5) only after the one-octave pattern is even. The new move is the thumb under finger 3.
6. Hands together come last, at the slower hand's tempo. Then play the three inversions as block chords so the ear knows the chord the arpeggio came from.

When the pattern is reliable, read it from the staff instead of from the finger numbers. The point of the drill is to see the chord and play it, not to memorise a diagram.
