Arpeggios in real music · From Zero to Mozart

Arpeggios aren't just practice material — composers write them into melodies and accompaniments constantly. Here's where you'll meet them, including the one this whole course has been pointing toward.

Alberti bass

The stock Classical keyboard accompaniment: a broken chord in the pattern low – high – middle – high, over and over, under a tune. Mozart's piano sonatas are full of it. You won't play it, but you'll see it in scores and hear it under everything.

96 bpm

An Alberti bass on the C major chord — low, high, middle, high. It's a C major arpeggio, just shuffled into a rocking pattern. Recognise the shape when you see it in a score.

The Mannheim rocket

A fast rising arpeggio that gets louder as it climbs — a dramatic curtain-up gesture the Mannheim orchestra made famous in the 1740s. You'll hear one at the very start of Eine kleine Nachtmusik.

100 bpm

A G major arpeggio, launched upward with a crescendo — a 'rocket'. The hairpin under it says get louder as you climb.

The first note of Mozart

Here it is. The Mozart Violin Concerto No. 3, K.216 — the summit this course points toward — opens its solo violin entrance with a G major chord, and then a G major arpeggio. The violin comes in high and falls D → B → G: that's scale degrees ^5 → ^3 → ^1, the tonic triad, broken downward.

72 bpm

A simplified version of the K.216 solo entrance: roll the G major chord up to the high G, then let the line fall through the arpeggio — G(^8), D(^5), B(^3), G(^1). If you've practised the G major arpeggio, you already know this shape. It isn't a wall; it's a chord you know, spread out.

You'll decode the real thing — the exact rhythm, the little turn, the finger numbers on the part — in The first note of Mozart, a few lessons from now. The point here: that opening is an arpeggio you can already play.

The three (four) kinds of number on a violin part

While we're looking at a real part, one thing that trips everyone up. A note on a violin part can have:

an Arabic number 1–4 next to it → a finger (0 = open string);
a Roman numeral I–IV, or "sul G / D / A / E" → a string (I is the E string);
a Roman numeral at the start of a passage, like "III." → a position;
and in an analysis, ^1–^7 → a scale degree.

Four different numbering systems. The "2" by the first note of K.216 means second finger — not second position, not the second string. Keep them straight and a dense part stops looking like code.

Try it

Try

Play the simplified K.216 entrance above: roll the chord bottom to top — open D, B (1st finger, A string), G (low 2, E string) — landing and holding on that high G. Then let the line fall: D (3rd finger, A string), B (1st finger, A string), G (3rd finger, D string). Slowly. You're playing the first gesture of a Mozart concerto. Reading it was the hard part, and you just did it.

The usual mistake

Seeing an arpeggio in a real piece and reading it note by note as if it were random — "D… then B… then G… what's the pattern?" There is no puzzle: it's a chord you already know, spread out in time. Recognise the shape first (is this the tonic triad? the dominant seventh?), and the notes come for free. The other mistake: playing a written-out arpeggio heavy, one weighted note after another. It should flow as one gesture — a ripple, not a staircase.
