English to German Art/Literary Music

To account for a vibrato, the vocal analyser has a pitch allowance, this pitch allowance allows singers to be slightly sharp or flat (above/below the note) and still score.
On occasion singers drift into this vibrato pitch allowance with a pure tone (without vibrato) and therefore they sing slightly sharp or flat but still score.
This pitch allowance was used across the entire series to be fair to all singers.
