About This Drill

ACT Reading: Humanities (Drill 1) is a Reading practice drill covering Humanities. It contains 5 original questions created by Brian Stewart, a Barron's test prep author with over 20 years of tutoring experience.

Humanities passages cover topics in art, music, architecture, philosophy, film, literature, and cultural history. As you read, pay attention to the author's perspective, the significance of specific examples, and the relationship between ideas. Questions may ask about the main idea, specific details, the author's purpose, vocabulary in context, or inferences supported by the passage.

Passage

HUMANITIES: This passage is adapted from the essay "Sound and Structure: The Architecture of Jazz Improvisation" by Delphine Marchetti (©2019, Music Quarterly Review). Jazz improvisation is sometimes described as spontaneous composition, music invented in the moment, shaped by nothing but inspiration and instinct. This description flatters the performer but misrepresents the art. What sounds like freedom is built on an elaborate framework of musical knowledge, accumulated over years of practice, that the improviser draws on so automatically it becomes invisible. The framework begins with harmony. In jazz, the underlying chord progression of a song, its harmonic structure, is the skeleton over which improvisation occurs. A skilled improviser does not play random notes; she plays notes that fit, tension notes that resolve, substitutions that transform the color of a chord while keeping it functional. This harmonic fluency is not memorized in the way you might memorize a phone number, but internalized the way a native speaker internalizes grammar: below the level of conscious thought, available instantly. Rhythm provides a second layer of structure. Jazz rhythm is organized around the concept of swing, which refers to a kind of elastic relationship between notes, some held slightly longer than written, some pushed slightly earlier, creating a forward momentum that is difficult to notate but immediately recognizable to the ear. Learning to swing is not a matter of following a rule; it requires absorbing thousands of hours of recorded performances until the feel becomes instinctive. What improvisation adds to this framework is conversation. Jazz is rarely performed alone; the improviser plays with a rhythm section whose members are also improvising within their roles, responding to what they hear in real time. A pianist comps differently behind a soloist who is playing in long, arching phrases than behind one who is playing short, staccato figures. A drummer shifts emphasis in response to a phrase that creates rhythmic tension. This constant responsiveness, which jazz musicians call "listening", is what distinguishes a live performance from a recording of one. The result is music that sounds free precisely because its makers have mastered the constraints that make freedom possible.

Questions & Explanations

Question 1. The main point of the passage is that:

  • A) jazz improvisation is a purely instinctive art form that requires no formal musical training according to the text.
  • B) jazz improvisation is built on an internalized framework of musical knowledge, not pure spontaneity. ✓
  • C) jazz has declined in quality because modern performers no longer emphasize harmonic fluency.
  • D) jazz improvisation is best understood as a form of musical conversation between performers.

Explanation: Choice B is correct. The passage's opening paragraph explicitly challenges the 'spontaneous' description of jazz, and the rest of the passage explains the harmonic, rhythmic, and conversational structures that underlie improvisation. Choice A describes the very misconception the passage argues against. Choice C introduces a quality decline not mentioned in the passage. Choice D describes one important element, the conversational aspect, but the passage's main point is broader, encompassing harmony, rhythm, and conversation together.

Question 2. According to the passage, how does a jazz improviser's harmonic knowledge differ from the way one might memorize a phone number?

  • F) Harmonic knowledge is memorized in a single sitting, while a phone number must be rehearsed repeatedly.
  • G) Harmonic knowledge is internalized below conscious thought, while a phone number is recalled deliberately. ✓
  • H) Harmonic knowledge can be written down in notation, while a phone number cannot be notated musically.
  • J) Harmonic knowledge is shared among all musicians, while a phone number is personal.

Explanation: Choice G is correct. The passage states that harmonic fluency is 'not memorized in the way you might memorize a phone number, but internalized the way a native speaker internalizes grammar: below the level of conscious thought, available instantly.' The distinction is between deliberate recall and automatic, unconscious availability. Choice F misrepresents how phone numbers are memorized. Choices H and J introduce distinctions not made in the passage.

Question 3. The passage most strongly suggests that the concept of 'swing' in jazz is:

  • A) a precisely defined rhythmic rule that can be learned by studying notation.
  • B) a quality that must be absorbed through extensive listening rather than learned from written rules. ✓
  • C) unique to jazz and absent from all other musical traditions.
  • D) primarily a function of the drummer's technique rather than the whole ensemble.

Explanation: Choice B is correct. The passage states that learning to swing 'is not a matter of following a rule' and 'requires absorbing thousands of hours of recorded performances until the feel becomes instinctive'; it cannot be learned from notation alone. Choice A contradicts this; the passage says swing is 'difficult to notate.' Choice C introduces a comparative claim about other musical traditions not made in the passage. Choice D singles out the drummer; the passage does not limit swing to any one instrument.

Question 4. As it is used in the passage, the word 'comps' most nearly refers to:

  • F) compensates for the soloist's errors.
  • G) accompanies the soloist with chordal support. ✓
  • H) competes with the soloist for the listener's attention.
  • J) completes the soloist's unfinished musical phrases.

Explanation: Choice G is correct. In context, the passage describes a pianist 'comping differently behind a soloist' depending on the soloist's phrase style, comping is the jazz term for accompaniment, typically using chords played in rhythmic patterns that support the soloist. Choice F introduces the idea of correction, which is not implied. Choice H suggests competition, which contradicts the passage's emphasis on responsiveness and collaboration. Choice J describes completing phrases, which is not what comping means.

Question 5. The final sentence of the passage, 'The result is music that sounds free precisely because its makers have mastered the constraints that make freedom possible', primarily serves to:

  • A) contradict the passage's earlier argument that improvisation relies on structure.
  • B) resolve the apparent paradox introduced in the opening paragraph. ✓
  • C) suggest that jazz performers should study classical music in order to improve.
  • D) argue that musical freedom is only available to highly trained professionals.

Explanation: Choice B is correct. The opening paragraph presents a tension: jazz sounds free, but it is built on structure. The final sentence resolves this by showing that the two are not contradictory, mastery of structure is precisely what enables the impression of freedom. Choice A misreads the sentence; it reinforces rather than contradicts the earlier argument. Choice C introduces classical music as a model, which the passage does not suggest. Choice D draws an exclusionary conclusion not made by the passage.
