"Uncertainty" ("Niepewność") is a composition by J. K. Pawluśkiewicz to the poetry of Adam Mickiewicz, which was recorded in several different interpretive versions. In our study we kept the melodic line from the recording, that appeared on the first studio album "Marek Grechuta & Anawa" (1970), while the arrangement of instruments is based on the recording from the album "Złote przeboje Marka Grechuty" from the STU theater (1990).
The set includes: the song score, sheet music and lyrics for the vocal (also with signed chords), notes for piano, synthesizer (optional in place of string instruments), violins and cello, sheet music and tablature for guitar and bass guitar as well as sheet music and tablature melody line for guitar, alto and tenor saxophone, trumpet and violin. Tablature are available in two versions - with or without rhythmic values.
