Reading double stops and chords
When two or more noteheads share one stem, they sound together. On a violin that's a double stop — two strings at once — or a chord of three or four. Stage 2 (two in a row, two at once, or a wobble) taught you to spot them; this lesson is about reading what they ask for. Playing them is Stage 6.
Two noteheads — a double stop
Three or four noteheads — a chord you roll
The bridge is curved — the bow can only truly catch two strings at a time. So a printed three- or four-note chord is rolled: fast, bottom to top, the lower pair then the upper pair, on one bow. You usually sustain only the top note or two.
In a line
One more, from the orchestra
In an ensemble part, div. ("divisi") means the section splits — half the players take the top note, half the bottom, and nobody double-stops. No div. on a stack means everyone plays the double stop. unis. or non div. puts them back on one line. As a soloist you don't act on it, but you'll see it in a score.
Try it
Try
Rest the bow on the open D and open A strings at once — the arm at the height that touches both — and draw one slow, flat bow. Aim for both strings speaking equally, no wobble between them. That balanced double stop is the foundation every chord is built on. Leave the three- and four-note chords for Stage 6.
The usual mistake
Reading a stack of noteheads as a fast arpeggio — one after another — instead of a simultaneous event. (The tell is the beam: side-by-side and beamed = sequential; stacked on one stem = together. Stage 2.) Trying to sustain all the strings of a big chord — you can't; roll it. And playing div. as a double stop.
