The contribution presents the results of a research on differences in development of air jet fluxes in labium of a rectangular organ flue pipe caused by different voicing adjustments. Air jets of tone starting transients were observed by laser PIV (particle image velocimetry) on a single transparent pipe with varied combinations of the upper lip height (cut-up), the flue slit area (breadth) and the windchest air pressure. Visualizations of the air jet velocity vectors will be linked to a development of sound pressure and descriptions of sound quality from a listening test.
