typical sharp and high-volume sound. A commonly used alternative way to play the snare drum is known as "cross-stick", "rim click", or "side-stick". This is done by holding the tip of the drumstick against the drum head and striking the stick's other end (the butt) against the rim, using the hand to mute the head. This produces a dry high-pitched click, similar to a set of claves, and is especially common in Latin and jazz music. So-called "ghost notes" are very light "filler notes" played in between the backbeats in genres such as funk and rhythm and blues. The iconic drum roll is produced by alternately bouncing the sticks on the drum head, striving for a controlled rebound. A similar effect can be achieved by playing alternating double strokes on the drum, creating a double stroke roll, or very fast single strokes, creating a single stroke roll. The snares are a fundamental ingredient in the pressed (buzz) drum roll, as they help to blend together distinct strokes that are then perceived as a single, sustained sound. The snare drum is the first instrument to learn in preparing to play a full drum kit. Rudiments are sets of basic patterns often played on a snare drum. Construction Snare drums may be made from various wood, metal, acrylic, or composite, e.g., fiberglass materials. A typical diameter for snare drums is 14 in (36 cm). Marching snare drums are deeper (taller) in size than snare drums normally used for orchestral or drum kit purposes, often measuring 12 in deep (tall). Orchestral and drum kit snare drum shells are about 6 in (15 cm) deep. Piccolo snare drums are even shallower at about 3 in (7.6 cm) deep. Soprano, popcorn, and firecracker snare drums have diameters as small as 8 in (20 cm) and are often used for higher-pitched special effects. Most wooden snare drum shells are constructed in plies (layers) that are heat- and compression-moulded into a cylinder. Steam-bent shells consist of one ply of wood that is gradually rounded into a cylinder and glued at one seam. Reinforcement rings, so-called "re-rings", are often incorporated on the inside surface of the drum shell to keep it perfectly round. Segment shells are made of multiple stacks of segmented wood rings. The segments are glued together and rounded out by a lathe. Similarly, stave shells are constructed of vertically glued pieces of wood into a
