<P> "Taps" is sounded during each of the military wreath ceremonies conducted at the Tomb of the Unknown Soldier every year, including the ones held on Memorial Day . The ceremonies are viewed by many people, including veterans, school groups, and foreign officials . "Taps" also is sounded nightly in military installations at non-deployed locations to indicate that it is "lights out", and often by Boy Scouts, Girl Scouts and Girl Guides to mark the end of an evening event such as a campfire . </P> <P> The melody of "Taps" is composed entirely from the written notes of the C major triad (i.e., C, E, and G, with the G used in the lower and higher octaves). This is because the bugle, for which it is written, can play only the notes in the harmonic series of the instrument's fundamental tone; a B - flat bugle thus plays the notes B - flat, D, and F. "Taps" uses the third, fourth, fifth, and sixth partials . </P> <P> "Taps" is a bugle call - a signal, not a song . As such, there is no associated lyric . Many bugle calls had words associated with them as a mnemonic device but these are not lyrics . A Horace Lorenzo Trim wrote a set of words intended to accompany the music: </P> <P> Day is done, gone the sun, From the lake, from the hills, from the sky; All is well, safely rest, God is nigh . Fading light, dims the sight, And a star gems the sky, gleaming bright . From afar, drawing nigh, falls the night . Thanks and praise, for our days,' Neath the sun,' neath the stars, neath the sky; As we go, this we know, God is nigh . Sun has set, shadows come, Time has fled, Scouts must go to their beds Always true to the promise that they made . While the light fades from sight, And the stars gleaming rays softly send, To thy hands we our souls, Lord, commend . </P>
