12 questions · 80% to pass · no timer. This longer test revisits both units in the level. 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.

Saving a lesson records reading only. Previous lesson completions have not been converted into passing scores. You can continue reading without a pass; the assessment remains unpassed.

Question 1

A player practises a slow ballad with a click at 40 beats per minute and finds they are consistently ahead of the click, by a wider margin than when they practise at 100 beats per minute. Using the synchronization evidence in lesson 52 and the timing arithmetic of lesson 51, which explanation is defensible, and what is the practical fix?

Question 2

A recorded keyboard tresillo is played back for two assistants at 90 beats per minute. One wants to quantise the part to straight sixteenths to correct 'untidy' timing, the other wants to leave it. Which arithmetic settles the dispute, and what would the correction actually change?

Question 3

A guitarist with a capo at the third fret plays an E shape, and a keyboardist plays G major as G3, B3 and D4. Comparing the guitar's lowest sounding note with the keyboard's, which part sounds higher, by what interval, and what are the frequency figures?

Question 4

A learner plans a 45-minute session on barre-heavy repertoire with headphones at a loud monitoring level, no warm-up, and continuous barre passages. Identify the two risks that the sources cited in this level actually name, and state the fix for each.

Question 5

A learner sings a melody in eighth notes while strumming quarter notes at 84 beats per minute and finds the singing is the part that collapses. Using the coordination reasoning of lesson 58 and the independence reasoning of lesson 56, what is the correct account of the load, and the first change to make?

Question 6

A swing tune is played at 100 beats per minute, where one beat is 0.600 seconds. One practitioner sets a click on every eighth note and another sets a click on beats two and four. Which setting supports the feel, and what is the timing reason?

Question 7

A piece has an eight-bar A section followed by a sixteen-bar B section at 90 beats per minute, with the B section built by doubling the harmonic rhythm and lifting the register an octave. State the two section durations and identify which of the changes is a hypermetric contrast of length rather than a change of surface.

Question 8

A song in G demands one barre chord, and the learner can place a capo at the third fret and use the open E, A and D shapes instead. Using the physical arithmetic of lesson 55 and the transposition arithmetic of lesson 54, what does each route cost and what does each develop?

Question 9

To make a second section sound different without adding an instrument, a player moves the same three-note voicing up an octave and doubles the root an octave below. Which parameters have changed, which have not, and what figure states the register change exactly?

Question 10

A 32-bar piece at 84 beats per minute is exported, and the resulting audio file is 94.929 seconds long rather than 91.429 seconds. Which explanation is most likely, and what should be checked before treating the difference as a performance problem?

Question 11

At 60 beats per minute a fingerstyle pattern has the thumb on the beat and the fingers on eighths, while the sung melody moves at two syllables per beat. Which stream should be simplified first, and what are the three intervals involved?

Question 12

A learner scores twelve out of twelve on this level's test questions and concludes that they can now perform, sing and record the piece to a usable standard. Which judgement is accurate, and what would count as evidence?
