AGO Music Theory & Sight-Reading 1 — Questions and Answers

Question 1: What is the key signature of A major?

1 sharp
2 sharps
3 sharps (Correct answer)
4 sharps

Correct answer: 3 sharps

The key signature of A major contains three sharps. These sharps are F#, C#, and G#. This specific combination of sharps is necessary to maintain the correct intervallic structure of the A major scale, ensuring that the half steps and whole steps fall in their appropriate places according to the major scale formula.

Question 2: What does the time signature 6/8 indicate?

6 quarter notes per measure
6 eighth notes per measure (Correct answer)
3 eighth notes per measure
2 eighth notes per measure

Correct answer: 6 eighth notes per measure

The time signature 6/8 indicates that there are six eighth notes per measure. The top number '6' specifies the number of beats or subdivisions, and the bottom number '8' indicates that an eighth note receives one beat or count. In compound meters like 6/8, these six eighth notes are typically grouped into two main beats, with each beat subdivided into three eighth notes, giving it a flowing, often dance-like feel.

Question 3: Which chord is the dominant in the key of C major?

F major
D minor
G major (Correct answer)
A minor

Correct answer: G major

In the key of C major, the dominant chord is G major. The dominant chord is built on the fifth scale degree of a major or minor key. Counting five notes up from C (C-D-E-F-G) identifies G as the fifth scale degree, and the chord built on G in the key of C major is G major. This chord creates a strong harmonic tension that typically resolves to the tonic (C major).

Question 4: Which clef is used for sight-reading pedal lines in organ music?

Treble clef
Alto clef
Bass clef (Correct answer)
Tenor clef

Correct answer: Bass clef

The bass clef is universally used for sight-reading pedal lines in organ music. Organ scores typically feature three staves: two for the manual (hand) parts and one for the pedal (foot) part. Since the pedal division plays the lowest notes on the organ, the bass clef, also known as the F clef, is the appropriate notation for these lower pitches, making them easy to read and interpret.

Question 5: What is an interval of a perfect fifth above C?

A
G (Correct answer)
E
F

Correct answer: G

An interval of a perfect fifth above C is G. To find a perfect fifth, you count five scale degrees up from the starting note, including the starting note itself. In the C major scale (C-D-E-F-G), the fifth note is G. This interval is considered 'perfect' due to its highly consonant sound and its fundamental role in Western harmony.

Question 6: Which term describes gradually getting louder?

Diminuendo
Crescendo (Correct answer)
Staccato
Legato

Correct answer: Crescendo

The term 'crescendo' describes the musical instruction to gradually get louder. It is an Italian dynamic marking, often abbreviated as 'cresc.' or indicated by a hairpin symbol opening to the right. This instruction guides performers to steadily increase the volume and intensity of the music over a period, building excitement or emphasis.

Question 7: What does a natural sign do to a note?

Raises it one semitone
Lowers it one semitone
Returns it to its natural pitch (Correct answer)
Adds a rest

Correct answer: Returns it to its natural pitch

A natural sign (♮) is an accidental that cancels any previous sharp or flat affecting a note. It restores the note to its original, unaltered pitch, regardless of whether the sharp or flat was indicated by a key signature or a preceding accidental within the same measure. This allows for temporary deviations from the established key without changing the overall key signature.

Question 8: What is the function of a key signature?

Defines the time signature
Shows tempo changes
Indicates sharps or flats in the key (Correct answer)
Marks rehearsal spots

Correct answer: Indicates sharps or flats in the key

The primary function of a key signature is to indicate which notes are to be consistently played as sharps or flats throughout a piece of music. Placed at the beginning of a staff, it defines the tonal center or key of the composition. This simplifies notation by eliminating the need to write individual accidentals for every affected note, making the music easier to read and understand.

Question 9: Which technique helps improve sight-reading skills?

Memorizing all notes
Only playing scales
Looking ahead while reading (Correct answer)
Playing very slowly

Correct answer: Looking ahead while reading

Looking ahead while reading, often referred to as 'pre-reading' or 'scanning,' is a highly effective technique for improving sight-reading skills. This involves training your eyes to read several notes or even measures in advance of what your hands are currently playing. By anticipating upcoming musical patterns, harmonies, and rhythms, you can maintain a smoother flow, reduce hesitations, and react more quickly to new musical information, leading to more accurate and continuous sight-reading.
