The 6 sample questions as a list
  1. A note sits on the third line from the bottom of the treble staff. Which note is it?

    A) C
    B) G
    C) D
    D) B
    D) B

    The treble lines from the bottom are E, G, B, D, F, so the middle line is B. D is the middle line of the bass staff, a common mix-up when switching clefs.
    Staff & Clefs
  2. A piece has six eighth notes per measure, felt as two beats that each divide into three. Which time signature fits?

    A) 3/4
    B) 6/8
    C) 2/4
    D) 12/8
    B) 6/8

    6/8 is compound duple: two dotted-quarter beats, each split into three eighths. 3/4 also holds six eighths but groups them in three pairs, giving three beats.
    Meter & Time Signatures
  3. A key signature has three flats. Which major key does it indicate?

    A) A♭ major
    B) D♭ major
    C) B♭ major
    D) E♭ major
    D) E♭ major

    The flats are B♭, E♭, A♭, and the second-to-last flat names the key: E♭ major. A♭ major has four flats, adding D♭.
    Key Signatures
  4. What is the interval from D up to B♭?

    A) Major sixth
    B) Augmented fifth
    C) Minor sixth
    D) Minor seventh
    C) Minor sixth

    D to B spans six letter names, so it is a sixth, and D up to B♭ is eight half steps: a minor sixth. D up to B natural would be the major sixth.
    Intervals
  5. In D major, which Roman numeral labels the B minor triad?

    A) ii
    B) IV
    C) iii
    D) vi
    D) vi

    B is the 6th degree of D major, and the triad B–D–F♯ is minor, so it is a lowercase vi. In D major, ii is built on E, iii on F♯ and IV on G.
    Diatonic Harmony & Cadences
  6. Which note name is the enharmonic equivalent of B♯?

    A) C
    B) B
    C) C♯
    D) A♯
    A) C

    B and C are only a half step apart, so raising B by a half step lands on the same key as C. C♯ would be a whole step above B.
