Find C and G major arpeggio notes, compare scales with chord tones, and use precisely scoped fingering examples.
C – E – G – C
Direction: Ascending · C4 → C5 · Semitone movement: 4 – 3 – 5
C major arpeggio: C - E - G - C. Root-position chord degrees 1-3-5-1.
The related C major scale contains C - D - E - F - G - A - B; this arpeggio uses only the root, third, and fifth.

An arpeggio presents chord tones one after another. This reference covers root-position C and G major triads. The C-major notes are C, E and G; the G-major notes are G, B and D. Repeating the root one octave higher gives a short ascending reference, followed here by the same notes descending.
The C-major scale reads C, D, E, F, G, A, B, C. Its tonic arpeggio uses C, E, G, C: degrees 1, 3, 5 and the octave. Compare the two note rows before playing. The arpeggio skips the intervening scale notes instead of moving through each degree.
G major has F-sharp in its scale, but the G-major tonic triad contains G, B and D. The one-octave arpeggio is G, B, D, G. The scale and arpeggio share a key label while containing different numbers of distinct notes.
The verified examples below cover C major in the right hand and G major in the left hand, each for one octave up and back. Their source prints every finger number. Follow the hand and register labels; these numbers are not a two-octave fingering chart. Other hand-specific examples remain to be checked.
Name the three chord tones, then read the short arpeggio upward and back. Compare it with the corresponding scale row. Work with one labeled hand example at a time, using the printed finger sequence only for its stated range.
An arpeggio presents chord tones in succession rather than all at once. These references use root-position major-triad tones, with the tonic repeated an octave higher.
The C major scale is C–D–E–F–G–A–B–C. The C major arpeggio selects scale degrees 1, 3 and 5, then repeats the tonic: C–E–G–C. It skips the intervening scale tones rather than changing their spelling.
The G major arpeggio uses G–B–D–G. The G major scale, by contrast, uses G–A–B–C–D–E–F#–G. F# belongs to that scale but is not a tone of the G major triad.
The sourced C example is right hand, C4–E4–G4–C5–G4–E4–C4, with 1–2–3–5–3–2–1. The sourced G example is left hand, G2–B2–D3–G3–D3–B2–G2, with 5–3–2–1–2–3–5. The separate G4–G5 treble reference is notes-only, with no assigned hand or fingering. Select one view; do not transfer the low-register G fingering to the treble reference. These are single-source, one-octave examples, not two-octave or teacher-reviewed prescriptions.
