Unit quiz: Independence, lines and form: right-hand clocks, keyboard voicings, singing, a second section, and one finished performance

Check understanding, separately from reading

5 questions · 80% to pass · no timer. This quiz checks the lessons in this unit. These authored questions assess recognition and application of the taught distinctions, not professional qualification. You may review the lessons and retry. Repeat attempts reuse the question bank; a remembered answer is not proof of transfer to a new situation.

Question 1

At 96 beats per minute a fingerstyle player's thumb sounds one bass note per bar while the fingers play eighth notes above it. What are the two intervals, and what does the ratio imply for practice?The thumb fires every 2.500 seconds and the fingers every 0.313 seconds, so the finger part carries eight times as many events and must become automatic on its own before the parts are combinedBoth parts run at the same interval of 0.625 seconds, because at any tempo the thumb and the fingers should share the beat

Question 2

A keyboardist plays F, A and C, and then plays F, A and C again an octave higher, describing the second voicing as an inversion that has changed the bass. Which description is correct under the inversion material of lesson 57?The second chord is F in second inversion, because raising a voicing by an octave changes which chord member is heard as the bassBoth chords are F major in root position; the second is the same voicing raised by 1,200 cents, and an inversion would need A or C in the bass

Question 3

A learner can sing the melody reliably alone and can play the accompaniment reliably alone, but the combination fails at every chord change. Which plan follows the evidence cited in lesson 58?Automate the accompaniment, plan the breath points, and combine one phrase at a time at a reduced tempo, because the two tasks recruit partially overlapping networks and one of them has to become cheapSing more loudly and play more firmly so that each part is strong enough to survive on its own, since overlapping tasks simply need more energy from both

Question 4

A songwriter's second section matches the first in tempo, phrase length and chord vocabulary, but listeners report no sense of arriving somewhere new. Which single change best creates the missing contrast while keeping the section related?Add a further layer and a doubled octave at a higher level, because contrast is produced by more content than the first section hadMove a categorical parameter: rotate the schema so a different chord begins the loop, or lift the upper part by an octave, which is 1,200 cents

Question 5

A learner exports a MIDI file of the finished piece and sends it as the recording, telling the recipient to listen to the performance. What is the problem, and what does the file contain?A MIDI file holds performance instructions rather than sound, so the recipient needs a sound source; only an audio render is a recordingThe MIDI file holds audio at a lower resolution, so the recipient will hear the piece but with reduced quality
