the traditional PAS rudiments #20 Flam and #31 Drag. A hybrid can also be created by adding a prefix before a rudiment or a suffix at the end of the rudiment in the form of extra notes or a rudimental pattern. There are certain characteristics that make a reasonable hybrid rudiment; The Rudiment cannot be too long as to where it extends beyond one measure (bar). The Rudiment needs to be symmetrical meaning that it may be played on the right or left. As an example; the rock beat cannot be a rudiment because the right-hand plays something completely different from the left. A few examples are the "Herta" which is a drag played with alternating sticking; the "cheese", a diddle with a grace note; and the "eggbeater", a five-tuplet with the sticking "rrrll." These hybrids have themselves given way to further hybrids; the "cheese invert" (an inverted flam tap with cheeses instead of flams) and the "diddle-egg-five" (a paradiddle-diddle followed by an eggbeater and two diddles, one on each hand). Other hybrid rudiments include: "book reports", "ninjas", and "flam dragons" (formerly known as "double flam drags"). Hybrid rudiments have been historically associated with modern marching band repertoire, especially Drum Corps International. The number of hybrid rudiments expanded rapidly starting in the 1990s. Today there are an indeterminate number, with more than 500 published and documented hybrid rudiments or unique variations. The latest innovation in hybrid rudiments has been "The Grid", which is a method for producing variations on a simple rudimental pattern by moving the individual elements of the rudiment (for example flams, accents, or diddles) through the notes of basic rhythm of the rudiment. One example of a Grid technique would be to play the PAS Flam Accent (a grace note and accent on the first of 3 single strokes) with the accent on the first note, then the second note, then the third note, producing 3 variations of the pattern and exhausting the placement options for the accent within the rhythm. The same could then be done with the grace note for the flam, producing 3 more patterns. The resulting 6 patterns could then be combined in a sequential way, producing further variations until all combinations of elements are exhausted. Not all of the resulting combinations are named or officially listed as rudiments, but are useful in developing a player's skills. See also Drum cadence References External
