How does a player produce different pitches and timbres on the berimbau?

Answers

Answer:

To produce different pitches and timbres on the berimbau, the player manipulates three key components of the instrument:

Tension of the string: The player can adjust the tension of the string by moving the small wooden wedge known as the "dobrão" up or down along the string. This changes the pitch of the string and allows the player to play different notes.

Position of the player's hand: By moving their hand up or down the length of the string, the player can change the sounding length of the string and produce different pitches.

Contact point of the stick: The player strikes the string with a stick or rod, known as the "vaqueta," at different points along the length of the string to produce different timbres. Striking the string closer to the gourd produces a deeper, more resonant sound, while striking the string closer to the player's hand produces a brighter, sharper sound.

The base drum that leads the ensemble and other percussion instruments in carnival is called:
Select one:
a. Pandero
b. Tamborino
c. Agogo
d. Surdo

Answers

The answer is d surdo

The base drum that leads the ensemble and other percussion instruments in carnival is called Surdo. Correct option is d.

The base drum that leads the ensemble and other percussion instruments in carnival is called a "Surdo." The Surdo is a large, cylindrical drum that originates from Brazil and is widely used in various styles of Brazilian music, particularly in carnival and samba performances.

Here's a more detailed explanation of the Surdo:

1. Role in Carnival: In Brazilian carnival and samba parades, the Surdo plays a crucial role as the heartbeat of the ensemble. It provides the foundational rhythm and sets the tempo for the entire group of percussion instruments and dancers. The deep, resonant sound of the Surdo is what gives samba music its infectious groove and energy, driving the dancers and musicians forward during the vibrant and lively carnival celebrations.

2. Design: The Surdo is typically quite large and cylindrical in shape. It comes in various sizes, with the larger drums producing lower pitches and the smaller ones producing higher pitches. The drum is usually made of wood or metal, and its head is covered with a synthetic skin (e.g., plastic or nylon) that can be tightened or loosened to adjust the pitch.

3. Playing Technique: The Surdo is played with mallets or beaters, one in each hand. The player strikes the drumhead with the beaters, creating a deep and booming sound. Surdo players use a specific technique to achieve a distinctive rhythm, often playing alternating low and high notes to maintain the rhythmic pattern.

4. Ensemble and Samba Schools: In carnival parades, large groups of musicians and dancers form ensembles or samba schools that showcase their performances in a coordinated and synchronized manner. The Surdo is one of the central instruments in these ensembles, driving the rhythm and providing a strong foundation for the rest of the percussion instruments, such as tamborims, agogôs, and pandeiros, as well as other instruments like cuicas and chocalhos.

In summary, the Surdo is a key instrument in Brazilian carnival and samba performances, responsible for leading the ensemble and setting the rhythmic pulse that brings the festivities to life. Its powerful and captivating sound makes it an integral part of the cultural expression and vibrant energy of Brazilian carnival celebrations.

The tango is a dance and music form that originated in the late 19th century in Argentina, particularly in Buenos Aires and Montevideo. The early controversies about the tango were mainly centered around social and cultural concerns, particularly regarding its origins and its perceived immorality.

The tango was first danced by working-class people in the suburbs of Buenos Aires, and was associated with the marginalized and immigrant communities of the city. As it gained popularity, it also gained a reputation for being a vulgar and immoral dance, associated with crime, pros-titution, and other forms of social deviance.

The dance's close embrace, intricate footwork, and sensual movements were seen as scandalous and provocative, particularly by more conservative elements of society.

7. What are Modernism and Postmodernism and how have they been expressed in art, music, and literature since 1945

Answers

Modernism and Postmodernism are two major cultural movements that have had a significant impact on the arts since 1945. Modernism is an artistic and literary movement that emerged in the late 19th and early 20th centuries, characterized by a focus on individualism, experimentation, and the rejection of traditional norms and values.

Modernism sought to break free from the constraints of traditional art and literature and to explore new forms of expression.

Postmodernism, on the other hand, emerged in the 1960s as a reaction to modernism. It is characterized by a focus on fragmentation, irony, and the rejection of grand narratives and universal truths. Postmodernism seeks to challenge the notion of objective reality and to explore the diversity of human experience and perspective.

In the realm of visual arts, modernism has been expressed through movements such as cubism, surrealism, and abstract expressionism, which sought to break down traditional forms and to explore new ways of representing the world. Postmodernism, on the other hand, has been expressed through movements such as pop art and conceptual art, which seek to challenge traditional notions of art and to explore the boundaries between art and everyday life.

In music, modernism has been expressed through movements such as atonality, serialism, and minimalism, which sought to break free from traditional tonal structures and to explore new forms of musical expression. Postmodernism, on the other hand, has been expressed through movements such as neo-romanticism and postmodernism, which seek to challenge the boundaries between different musical genres and to explore the diversity of musical styles and cultures.

In literature, modernism has been expressed through works such as James Joyce's Ulysses and Virginia Woolf's Mrs. Dalloway, which sought to break free from traditional narrative structures and to explore new forms of storytelling. Postmodernism, on the other hand, has been expressed through works such as Thomas Pynchon's Gravity's Rainbow and Salman Rushdie's Midnight's Children, which challenge traditional notions of authorship and narrative authority and explore the complexities of identity and representation.

If you attend a play that features a chorus and masked actors and has violence that occurs only offstage, you are probably watching a Greek tragedy. Greek tragedies are known for their use of a chorus, which is a group of actors who serve as a narrator or commentator on the action of the play.

The use of masked actors was also common in Greek theater, as it allowed actors to play multiple roles and to portray characters who were not human, such as gods or monsters.

The fact that the violence in the play occurs only offstage is another characteristic of Greek tragedies. The Greeks believed that the most dramatic moments in a play should happen offstage, as it allowed the audience to use their imagination and to create their own mental images of the events that were occurring.

Overall, Greek tragedies were a form of storytelling that focused on exploring the human condition and the nature of fate and destiny. They were often dark and tragic, but they also had a certain beauty and poetry to them.

Show the appropriate SQL statements. Can Joe read the DeptInfo view?10. After returning from your (wonderful) vacation, you see a note from Joe, indicating that he authorized his secretary Mike to read the Employees relation. You want to revoke Mikes SELECT privilege on Employees, but you do not want to revoke the rights you gave to Joe, even temporarily. Can you do this in SQL?11. Later you realize that Joe has been quite busy. He has defined a view called All-Names using the view EmployeeNames, defined another relation called StaffNames that he has access to (but you cannot access), and given his secretary Mike the right to read from the AllNames view.

You decide that, even at the cost of annoying Joe by revoking some of his privileges, you simply have to take away Mike and Susans rights to see your data. What REVOKE statement would you execute? What rights does Joe have on Employees after this statement is executed? What views are dropped as a consequence? What is the name of the first king of denmark?
