Cossack Dance

"Cossack Dance" is a dance piece, not a song. The etymology of "Cossack" varies, referring to a military order or meaning "free man." First, seeing is believing. Please watch this.  If this link is deleted, please search for "Cossack" on YouTube. The link above is precisely this piece. As you can see from the video, this piece is extremely fast. Therefore, it is played at a fast tempo, which can lead to problematic sections. These are the 16th notes in measures 2, 4, 6, 8, and between measures 17-18. Regarding fingerings, all 16th note sections use 3231. A 2 always follows 3231. In places like measure 4, an eighth note ascends after the 16th notes. Therefore, the fingering 3231 2 might not feel unnatural. However, in patterns where an eighth note descends after the 16th notes, such as in measure 8, 3231 2 feels unnatural. The author also tried various options. One possibility is 4342 1.  However, after playing it several times, 3231 2 consistently feels easier to play. This fingering avoids involvement of fingers 4-5, so for children whose fingers are not yet independent, starting with 3 might be safer.  Musically, the key is to play energetically without stopping.
