Beautiful sound. Sarap pampatulog :) Sa atin kasi hilig natin palakpakan palagi. Kadalasan pag ganyan sa huli ang clapping. There was one musical event I atttended to and the composer didn't like to hear noise. After one certain song may mga nagingay sa audience. Humarap si composer/director sa audience and glared in the direction of the noise. When everyone quieted down, then he resumed. About the formal attire, it's not really required I think but just be decent enough :D
