The phrase represents a musical arrangement for a choir. Specifically, “SATB” indicates that the arrangement is written for four voice parts: Soprano, Alto, Tenor, and Bass. “Martin” likely refers to the composer or arranger of the piece. The initial words, “above the clear blue sky,” strongly suggest the title of the composition.
Such arrangements enable choral groups to perform pieces with richer harmonies and textures than would be possible with unison or two-part singing. The SATB format is a standard configuration for many choral works, offering a balance of vocal ranges and allowing for a variety of musical effects. The title itself may evoke imagery or emotions that are then conveyed through the musical composition, enriching the listening experience.
