Finger Numbers — Both Hands

Both hands use the same numbering system: 1 = thumb, 5 = pinky.

Left Hand (LH)

         5        4        3       2      1
         |        |        |       |      |
      PINKY    RING    MIDDLE   INDEX   THUMB
         \       |        |       |      /
          \      |        |       |     /
           \_____|________|_______|____/
                  LEFT HAND
            (plays lower notes)

Right Hand (RH)

    1      2       3        4        5
    |      |       |        |        |
  THUMB  INDEX  MIDDLE    RING    PINKY
    \      |       |        |       /
     \     |       |        |      /
      \____|_______|________|_____/
              RIGHT HAND
          (plays higher notes)

Key Points

• Finger 1 is always the thumb for BOTH hands
• Finger 5 is always the pinky for BOTH hands
• Fingers 2, 3, 4 are index, middle, ring for BOTH hands
• When reading fingering numbers, they always refer to the SAME finger regardless of hand
• Keep fingers curved, like holding a small ball

Common Scale Fingering Patterns

C Major Scale — RH

Notes: C D E F G A B C

Finger: 1 2 3 1 2 3 4 5

^

thumb crosses under

After finger 3 plays E, tuck the thumb (1) under to play F. This is called thumb-under crossing.

C Major Scale — LH

Notes: C D E F G A B C

Finger: 5 4 3 2 1 3 2 1

^

finger 3 crosses over thumb

After the thumb (1) plays G, finger 3 crosses over the thumb to play A. This is called finger-over crossing.

Standard Fingering Groups

Most major scales follow one of these patterns:

Group 1 — “Standard” (C, D, E, G, A, B Major):

RH: 1-2-3-1-2-3-4-5

LH: 5-4-3-2-1-3-2-1

Group 2 — Starts on black key (Db, Eb, Ab, Bb Major):

• Fingering varies; thumb lands on white keys
• General rule: thumb avoids black keys when possible

Group 3 — F Major (unique):

RH: 1-2-3-4-1-2-3-4

LH: 5-4-3-2-1-3-2-1

Common Chord Fingering Patterns

Basic Triads — Root Position

Chord Type	RH	LH
Most major triads (all white keys)	1 - 3 - 5	5 - 3 - 1
Most minor triads (all white keys)	1 - 3 - 5	5 - 3 - 1
Triads with black key in middle	1 - 3 - 5	5 - 3 - 1
Triads starting on black key	2 - 3 - 5	5 - 3 - 2

C Major Chord — Example

RH: play C(1) E(3) G(5) together

thumb middle pinky

 

LH: C(5) E(3) G(1) together

pinky middle thumb

Simplified: For LH chords, the lowest note gets the highest finger number.

	Lowest Note	Middle Note	Highest Note
RH	1 (thumb)	3 (middle)	5 (pinky)
LH	5 (pinky)	3 (middle)	1 (thumb)

A Minor Chord — Example

RH: A(1) C(3) E(5)

LH: A(5) C(3) E(1)

Same 1-3-5 / 5-3-1 pattern — works for any triad on white keys.

Inversion Fingering

Inversion	RH	LH
Root Position	1 - 3 - 5	5 - 3 - 1
1st Inversion	1 - 2 - 5	5 - 3 - 1
2nd Inversion	1 - 3 - 5	5 - 2 - 1

Thumb-Under Technique

When playing scales, the thumb needs to pass under fingers 2-3 (or 2-3-4) to reach the next note smoothly.

How it works (RH ascending):

1. Play notes with fingers 1-2-3
2. While finger 3 holds its note, smoothly pass thumb under the hand
3. Thumb lands on the next note
4. Continue with 2-3-4-5

How it works (LH descending):

1. Play notes with fingers 1-2-3
2. While finger 3 holds its note, pass thumb under
3. Thumb lands on the next note
4. Continue with 2-3-4-5

Common mistakes to avoid:

• Lifting the wrist to make room (keep wrist level)
• Twisting the hand sideways (keep palm facing down)
• Rushing the crossing (practice slowly)

Quick Lookup: Which Finger Plays What?

Finger	Name	Typical Use
1	Thumb	Scale crossings, chord roots (RH) or tops (LH)
2	Index	Strong, independent — scale passages
3	Middle	Strongest finger — chord middles, scale passages
4	Ring	Weakest finger — needs extra practice for independence
5	Pinky	Chord tops (RH) or roots (LH), melody high notes
