The slap tongue articulation is a unique sound and challenging technique in the performance of literature for the saxophone that has been used in a wide range of musical media, from classical to jazz. The purpose of this investigation is to gain a deeper understanding of the musical, artistic, and technical aspects of the slap tongue articulation as applied to the performance of selected, original literature for the alto saxophone. During the recital, the examples from Jungle by Christian Lauba, Rock Me by Barry Cockcroft and Pulse by Vincent David for unaccompanied alto saxophone were presented to demonstrate how to apply the slap tongue articulation artistically and effectively.
