1) The word 'snare' can be short for 'snare drum'. The 'snare' itself is the metal chain/belt thing that sits underneath the drum and gives it it's distinctive sound. The snare underneath a snare drum can be moved onto and off the drum with a lever, therefore 'snare on' and 'snare off' would refer to moving the snare onto the bottom of the drum, or taking it off. 2) The 'dynamic' is how loud or quiet the sound is. With percussion, that would relate to striking the drum at a greater distance or with more speed for louder playing, or more softly and gently for a quieter sound. Dynamics can be altered by where you strike the drum also, with louder sounds typically coming from the middle of the drum skin (part of the drum that is struck). I'm not a drummer myself and you probably know all this, but this is what dynamics are about :) 3) Bars are the individual sections of music on a music score (sheet music) between the vertical lines. 1 bar is 1 section. In 4/4 time (standard time signature) there are 4 beats or notes in a bar. I hope this makes sense, it would be easier to explain visually!

1. A snare is one of the round drums you might see on a drum set or played in a marching band. It is VERY loud. 2. In music, dynamics mean volume. How loud or soft you play the music. 3. If you look at a sheet of music, groups of notes are separated by vertical lines. One section of notes is a measure, or bar. So if you play a few bars, it is a very short segment of a piece. I hope this helps!

Q1: Liam is correct re: "snares off". A snare drum has a set of wires at the bottom that give it that sharp "TACK" sound. Those are called the snares. Snare drums have a switch, with which you can lower the snares to give the drum a rounder, less sharp sound. "Snares on" means the snares are raised, producing that characteristic snare drum sound. "Snares off" means the snares are lowered, producing a rounder, more generic drum sound. Q2: If a musician is told the dyamic, they're told "f" (forte, = loud), "mf" (mezzoforte = medium-loud), p (piano = soft) Q3: Liam's answer was perfect, I've nothing to add.
