Drum

The drum is a member of the percussion group of musical instruments. In the Hornbostel-Sachs classification system, it is a membranophone. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a drum stick, to produce sound. There is usually a resonance head on the underside of the drum, typically tuned to a slightly lower pitch than the top drumhead. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.

Drums may be played individually, with the player using a single drum, and some drums such as the djembe are almost always played in this way. Others are normally played in a set of two or more, all played by the one player, such as bongo drums and timpani. A number of different drums together with cymbals form the basic modern drum kit.

Tholobate

A tholobate or drum, in architecture, is the upright part of a building on which a dome is raised. It is generally in the shape of a cylinder or a polygonal prism.

In the earlier Byzantine churches, the dome rested direct on the pendentives and the windows were pierced in the dome itself; in later examples, between the pendentive and the dome an intervening circular wall was built, in which the windows were pierced, and this is the type which was universally employed by the architects of the Renaissance, of whose works the best-known example is St. Peter's Basilica at Rome. Other examples of churches of this type are St Paul's Cathedral in London, and the churches of the Les Invalides, the Val-de-Grâce, and the Sorbonne in Paris.

Music

Bass (sound)

Bass (/ˈbeɪs/ BAYSS; Italian: basso, deep, low) describes tones of low frequency or range from 16-256 Hz (C0 to middle C4). In musical compositions, these are the lowest parts of the harmony. In choral music without instrumental accompaniment, the bass is supplied by adult male bass singers. In an orchestra, the bass lines are played by the double bass and cellos, bassoon and/or contrabassoon, low brass such as the tuba and bass trombone and the timpani (kettledrums). In many styles of traditional music such as Bluegrass, folk, and in styles such as Rockabilly and jazz, the bass role is filled by the upright bass. In most rock and pop bands and in jazz fusion groups, the bass role is filled by the electric bass. In some 20th and 21st century pop genres, such as 1980s pop and Electronic Dance Music, the bass role may be filled with a bass synthesizer.

Musical role

Played in a musical ensemble such an orchestra, such notes are frequently used to provide a counterpoint or counter-melody, in a harmonic context either to outline or juxtapose the progression of the chords, or with percussion to underline the rhythm. In popular music the bass part most often provides harmonic and rhythmic support, usually playing the root or fifth of the chord and stressing the strong beats. "The bass differs from other voices because of the particular role it plays in supporting and defining harmonic motion. It does so at levels ranging from immediate, chord-by-chord events to the larger harmonic organization of a entire work."

Sugar

Sugar is the generalized name for sweet, short-chain, soluble carbohydrates, many of which are used in food. They are carbohydrates, composed of carbon, hydrogen, and oxygen. There are various types of sugar derived from different sources. Simple sugars are called monosaccharides and include glucose (also known as dextrose), fructose and galactose. The table or granulated sugar most customarily used as food is sucrose, a disaccharide. (In the body, sucrose hydrolyses into fructose and glucose.) Other disaccharides include maltose and lactose. Longer chains of sugars are called oligosaccharides. Chemically-different substances may also have a sweet taste, but are not classified as sugars. Some are used as lower-calorie food substitutes for sugar described as artificial sweeteners.

Sugars are found in the tissues of most plants, but are present in sufficient concentrations for efficient extraction only in sugarcane and sugar beet. Sugarcane refers to any of several species of giant grass in the genus Saccharum that have been cultivated in tropical climates in South Asia and Southeast Asia since ancient times. A great expansion in its production took place in the 18th century with the establishment of sugar plantations in the West Indies and Americas. This was the first time that sugar became available to the common people, who had previously had to rely on honey to sweeten foods. Sugar beet, a cultivated variety of Beta vulgaris, is grown as a root crop in cooler climates and became a major source of sugar in the 19th century when methods for extracting the sugar became available. Sugar production and trade have changed the course of human history in many ways, influencing the formation of colonies, the perpetuation of slavery, the transition to indentured labour, the migration of peoples, wars between sugar-trade–controlling nations in the 19th century, and the ethnic composition and political structure of the New World.

Jesse Porter

Jesse Porter (Coby Bell) is a former Counterintelligence Field Activity/Defense Intelligence Agency agent introduced in the Season 4 premiere. He was initially stationed in the field, but his risky and impulsive tactical maneuvers led to his being demoted to desk duty. Because of his research on the war-profiteering organization that Management was hunting, Michael stole Jesse's work in the course of his investigation, unintentionally burning Jesse. Jesse came to Michael for help as a fellow burned spy, which Michael accepted. But the fact that Jesse was insistent on exacting revenge on whoever burned him led the team to cover their trails leading to his burning. Left with nothing as Michael was, Jesse moves in as a tenant with Madeline and quickly fits into the team and their regular jobs.
