The treble baglamas is pitched an octave higher (nominally D–A–D), with unison pairs on the four highest strings and an octave pair on the

Modern "synthetic gut" is actually a multi-filament string that holds its tension extremely well and which has a dynamic stiffness profile that is closest to natural gut, although the industry continues to apply the term to mono-filament nylon strings. Multi-filament strings, known commonly as "multis"
