In accordance with AR 220–90, 'Echo or Silver Taps', which is performed by two buglers, is not authorized." Field Manual 12–50, U.S. Army Bands, dated October 1999, Appendix A, Official And Ceremonial Music, Appendix A, Section 1 – Ceremonial Music, Paragraph A-35 "A-35. Signals that unauthorized lights are to be extinguished. This is the last call of the day. The call is also sounded at the completion of a military funeral ceremony. Taps is to be performed by a single bugler only. Performance of 'Silver Taps' or 'Echo Taps' is not consistent with Army traditions, and is an improper use of bugler assets." Many Scouting, Girl Scouts and Guiding groups around the world sing the first verse of "Taps" ("Day is Done...") at the close of a camp or campfire. Scouts in encampment may also have the unit's bugler sound taps once the rest of the unit has turned in, to signify that the day's activities have concluded and that silence is expected in the camp. Within the Girl Guides of Canada, it is tradition to sing the third verse ("Thanks and praise...") if the closing is done during daytime.
