Abstract: Considering the end-user perception of music, acoustics is as im- portant as any other component, obvious for a non-engineer listener, like timbre of the instruments, the harmony and the overall quality of a performance. In November 2015 a very special set of concerts was performed at AGH Universi- ty of Science and Technology, where extreme acoustic conditions were present- ed. The same compositions were played in an anechoic chamber, a reverbera- tion chamber and underwater, presenting to the listeners totally different per- ception of music, also the Ruben's Tube (also called a pyro tube) experiment with vocals/instruments was presented visualizing the standing wave phenome- non. The paper will explain the principles of used acoustic environments, in- cluding numerical simulation of underwater sound propagation. One of the used environments was AGH swimming pools, where the participants of the experi- ment were listening to the music underwater. Waterproofed loudspeakers were used to perform the concert; FEM simulations will explain how the music prop- agates underwater and how it influences the frequency response of the music. The project efficiently joined the scientific and artistic approach to the music - for the musicians to prepare and perform the compositions and the scientists to prepare and explain the acoustics. The overall evaluation of the performance was prepared and presented in the paper. Conclusions will discuss the objective and subjective changes in the perception of instruments and musical works, af- ter scientific presentation of the acoustics influence on the listener.
