Make some chords

So far every column held one note at a time. Click several rows in the same column and they play together: that is a chord.

The most common chord is a triad: three notes, each one row apart from the next (1, 3 and 5). Skipping a row each time gives the notes room, so they blend instead of rubbing.

Your turn

Here only the 1 is set. Add the 3 and the 5 above it, then try building the same shape starting on other rows.
