Drum roll

A drum roll (or roll for short) is a technique the percussionist employs to produce, on a percussion instrument, a sustained sound, "over the value of the written note." Rolls are used by composers to sustain the sound and create other effects, the most common of which is using a roll to build anticipation.

Types

Snare drum roll

A common snare drum roll is the closed (or "buzz" or "concert") roll. The concert roll is performed by creating 3 equal sounding bounces on each hand alternating right to left. The 3 bounces are made even more equivalent in sound by using the acoustic properties of the snare drum. Strokes closer to the rim will have a lower volume than strokes on or near the sweet spot of the drum. Therefore by placing the first of the 3 bounces closer to the rim and moving the second bounce towards the sweet spot and finally the third bounce in the sweet spot will produce three equal sounding bounces.

The open roll (or "double-stroke roll") is played with double strokes alternating between the left and right hands. Using a forearm stroke for the first and the fingers for the second stroke, the 2 strokes can be made to sound identical. This produces a near-continuous sound when the technique is mastered.

Drum (2004 film)

Drum is a 2004 film based on the life of South African investigative journalist Henry Nxumalo, who worked for the popular Drum magazine, called "the first black lifestyle magazine in Africa." It was director Zola Maseko's first film and deals with the issues of apartheid and the forced removal of residents from Sophiatown. The film was originally to be a six-part television series called Sophiatown Short Stories, though Maseko could not get the funding. The lead roles of Henry Nxumalo and Drum main photographer Jürgen Schadeberg were played by American actors Taye Diggs and Gabriel Mann, while most of the rest of the cast were South African actors.

The film premiered at the Toronto International Film Festival in September 2004, and proceeded to do the rounds of international film festivals before going on general release in South Africa in July 2006. It was released in Europe, but failed to get a distributor for the USA where it went straight to DVD.

The film was generally well received critically. Most of the negative reviews were based on the quality of Maseko's directing and Jason Filardi's screenwriting. It was awarded Best South African Film at the Durban International Film Festival, and director Maseko gained the top prize at the Panafrican Film and Television Festival of Ouagadougou (FESPACO).

Drum (yacht)

Drum is a maxi yacht formerly co-owned by lead singer of Duran Duran Simon le Bon and currently owned by Scottish businessman Sir Arnold Clark.

Design

Drum was designed by Ireland-based boat-builder Ron Holland and built in Finland.Drum was purpose-designed and built to be sailed in the Whitbread Round the World Race.

Career

Fastnet, 1985

Drum competed in the 1985 Fastnet Race. It was one of the favorites to win the race, but the boat lost its keel due to a design failure and capsized. Its crew were all rescued.

1985–86 Whitbread

Drum was re-fitted and competed in the 1985–86 Whitbread Round the World Race.

Current status

As of 2013 Drum is owned by Scottish businessman Arnold Clark, who purchased the yacht in the late 1980s. In 1988 Drum was accorded media attention when it was involved in a collision with a Royal Navy submarine.

Euler angles

The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body. To describe such an orientation in 3-dimensional Euclidean space three parameters are required. They can be given in several ways, Euler angles being one of them; see charts on SO(3) for others. Euler angles are also used to describe the orientation of a frame of reference (typically, a coordinate system or basis) relative to another. They are typically denoted as α, β, γ, or φ, θ, ψ.

Euler angles represent a sequence of three elemental rotations, i.e. rotations about the axes of a coordinate system. For instance, a first rotation about z by an angle α, a second rotation about x by an angle β, and a last rotation again about y, by an angle γ. These rotations start from a known standard orientation. In physics, this standard initial orientation is typically represented by a motionless (fixed, global, or world) coordinate system; in linear algebra, by a standard basis.

Any orientation can be achieved by composing three elemental rotations. The elemental rotations can either occur about the axes of the fixed coordinate system (extrinsic rotations) or about the axes of a rotating coordinate system, which is initially aligned with the fixed one, and modifies its orientation after each elemental rotation (intrinsic rotations). The rotating coordinate system may be imagined to be rigidly attached to a rigid body. In this case, it is sometimes called a local coordinate system. Without considering the possibility of using two different conventions for the definition of the rotation axes (intrinsic or extrinsic), there exist twelve possible sequences of rotation axes, divided in two groups:
