Historically because of the complicated mountain geography of the region, and due to other factors, in some regions each community would develop its own type of siku, with its own special tuning, shape and size. Additionally each community developed its own style of playing. Today the siku has been standardized to fit in with modern western forms of music and has been transported from its traditional roots.

, where a woman would play her siku as she came down from the mountains. Since the largest siku has every note (A-G), and was too big for the woman, they often got two sikus (usually smaller ones) that would be played together with someone else, so they could play them continuously after each other and thus the scales could fully be played. Once the women partnered, they then became musically bonded with each other, as part of their religion, and neither could play the pipes with any other for the rest of their life.
Women would also assemble into groups as they came down the mountains, each group would play different tunes, and as they got together, they would blend all the melodies together to create one complete melody. The woman also played the siku to attract wild goat that they would then harvest.

Songo, or shallow-walled bamboo, gives a louder, more resonant sound than regular deep-walled bamboo, but is less common due to its fragility.

'') that grows in the ''ceja de la selva'', literally "the eyebrow of the forest". The pipes are held together by one or two strips of cane (ties) to form a trapezoidal plane (like a raft). Antaras are of different sizes and they produce diverse sounds.
Siku is split across two rows of pipes. One must alternate rows with every note in order to play a complete scale. Traditionally, two musicians were required to play the siku, each one taking one row of the instrument. One part of the instrument is called ''ira'', another ''arka''. It is considered that spiritually ''ira'' corresponds to male principle and ''arka'' to female. When many musicians divide in two parts, first playing ''ira'' and second playing ''arka'', this gives

Varieties
The most widespread variety of siku, ''siku ch'alla'', contains 13 pipes (6 in ''ira'' and 7 in ''arka''), but less common varieties may have more and fewer pipes. Some of them employ extra open-ended reeds attached to the front of the instrument to change the sound quality. The ''tabla siku'' has all of the pipes cut to the same length, so the instrument is rectangular in shape but has stoppers inside the tubes to adjust the actual resonant length of the chambers.
Scale and tuning
The siku uses a
