Drum roll

As vertebrates a figure is called playing the drums at the follow many individual strokes in such rapid succession that they are no longer perceived as single strokes, but by the human ear as a lasting, uniform noise.

The classical vortex technique consists of a sequence of left and right double beats, in each of which the first beat is actively managed and then recoiling from fur Schlegel is subsequently forced to a second shock. This technique is sometimes also called mill or mom - dad ( or dad - mom ).

In addition to this double whammy eddy eddy other techniques are applied, depending on the style of music and used drum so the single impact vertebrae ( eg on the kettledrum ), or vertebral compression (eg on the classic snare drum ).

In the notes are either quoted directly the individual strokes (usually 32nd ), the vortex can also be listed as a trill or tremolo. In a marching band there is also some places traditional drum notation with symbols that can be very different landscapes (eg the Basel drums ).

Various vertebrate species

There are several types of vortices:

• Open vertebrae (Open Stroke Roll)
• Closed vortex (Closed Roll, Buzz Roll or press vertebrae)
• Handed vertebrae ( One handed roll / Gravity Roll)
• Single impact vertebrae ( Single Stroke Roll)

Open eddy: An open vortex is generated with controlled double beats by leading the energy of the first blow in the second shot after the " rebound" ( springing back of the drum beater ).

Closed vortex: A closed vortex is generated with non-controlled press beats by the drums Schlegel is pressed onto the skin and are generated by the " rebound" as many punches per hand. The more beats per hand can be generated, the denser sounds of the vertebrae.

Single impact vortex: The single impact is the only vertebrate vertebrate, which is not produced by double or multiple strokes. In this style, only single strokes are played. This is usually done with a series of right and left single strokes.

Handed vortex: The one handed roll is different from all other vertebrae in that it is not a series of right and left multiple strokes. Instead beats are produced in rapid succession as possible in this vortex with only one hand, by the flail alternately performs a stroke, for example, with the wrist and fingers (push pull technique). It is simpler, however, to take the edge of the drum to help ( Johnny Rabb calls this technique " Freehand Technique" )

Applications

The various vertebrae differ in tone: While single-stroke and double stroke swirl a vortex arise in which each individual beat is heard or want to hear, produce the other techniques a fine and uniform vortex, which is intended to simulate a continuous tone. Which vertebrae should be used, depends heavily on the style of music.

All consisting of double strokes techniques can be applied on all drums. The closed vortex only works on high-tensioned drums such as snare drum or bongos good. The single impact vortex is mainly due to the timpani or mallet instruments (xylophone, marimba, vibraphone ), but also on all instruments that do not generate sufficient rebound ( pool, large orchestra drum, tom-toms, etc.), applied.

In the orchestral music of the closed vortex is mainly used in the marching music of the band, for example, in the German and Austrian area even exclusively. In the drum corps around the world, however, in Drum -and- Pipe - groups ( Duddelsackpfeifer with drummers ) in drum trains and quite generally in the rudimental drumming the open vortex is almost exclusively used - the use of closed vortex is very rare and is then explicitly specified in the notes.
