In unisons, the note given by the open string is produced simultaneously on the next lower string. The fingering adjusts itself according to the position in which one is playing, and it may be practised in the first four positions.
Seconds:
At a, the lower note will be played on the lower string, but at b the upper note is produced on the lower string. The fingering at a is conformable to the position employed—either the 3ʳᵈ, 2ⁿᵈ or 1ˢᵗ finger may be on the lower note. At b, the upper note can be played either in the 2ⁿᵈ, 3ʳᵈ, 4ᵗʰ or 5ᵗʰ position and either the 4ᵗʰ, 3ʳᵈ, 2ⁿᵈ or 1ˢᵗ finger may be placed on the upper note.
