The most popular Kyrgyz traditional instrument is komuz. While it’s fretless, the tradition around it isn’t part of maqam traditions, the music is rather standard diatonic. The standard way of performing on komuz is playing solo. Virtuoso players are called komuzchu “комузчу” (plural komuzchular “комузчулар”), they are also composers of new pieces.
There are songs and instrumental pieces. Instrumental pieces are called küü “күү” (plural küülör “күүлөр”) and comprise a core of the tradition (standards). There’s around 200 of popular ones, with the core of around 50 is the most popular. Some of them are traditional, some of them are composed by composers of the 20th century. The names of popular standards split by genres are given here. Their recordings can be found on YouTube.
The book “Балбай Алагушов. Антология кюу для комуза” (unavailable online, its CDs and DVDs are also unavailable) contains scores for many of them. Here’s a first part of photos (the second half to be photocopied):
Some speculations (to be carefully verified using the scores):

Speculations came from skimming В. Виноградов, Киргизская народная музыка, 1958 г. (not avaiable online).

Here comes the list of YouTube videos that closely match the scores from the book:
Kerbezim is a short piece by Toktogul Satylganov. It uses the first five notes of the A major scale (A-B-C#-D-E). The strings are tuned E3-A3-E3. The unusual sound comes from the droning fifth degree (not a tonic) - the upper E3 string. The lower A3 and E3 strings are used for the melody in the second (or the third?) position using the (imaginary) frets 4, 5 and 7. The A is played with the second string open (making a unison), on all other notes one of the two melodic strings is muted.
