Instrumentation and Performance Context

Which set best represents the woodwind forces used in the 1795 performance of Haydn’s London Symphony No.104, Movement 1?

• 1 flute, 2 oboes, 2 clarinets in B♭, 2 bassoons

• 2 flutes, 2 oboes, 1 clarinet in A, 2 bassoons

• 2 flutes, 1 oboe, 2 clarinets in A, 1 bassoon

• 2 flutes, 2 oboes, 2 clarinets in A, 2 bassoons

Answer explanation

The correct set for Haydn’s London Symphony No.104, Movement 1, includes 2 flutes, 2 oboes, 2 clarinets in A, and 2 bassoons, reflecting the standard orchestration of the time, which emphasizes the richness of woodwind textures.

In this symphony’s first performance, which instruments were noted as transposing instruments that also faced pitch limitations due to technology of the time?

• Timpani and double basses with tuning locks

• Clarinets, horns, and trumpets without valves

• Flutes, oboes, and bassoons with keys

• Violins, violas, and cellos with gut strings

Answer explanation

The correct choice is 'Clarinets, horns, and trumpets without valves' as these instruments were transposing and had pitch limitations due to the lack of valves, which restricted their range and tuning capabilities.

Why might clarinets in A have been preferred over B♭ clarinets for the 1795 performance of this symphony?

• They were easier for amateurs to play

• They allowed wider chromatic agility

• They projected better in large halls

• They suited tuning for a work in D major

Answer explanation

Clarinets in A are better suited for works in D major, as they match the key's tuning, allowing for more harmonious integration with the orchestra. This makes them preferable for the 1795 performance of the symphony.

A conductor asks you to explain why brass melodies in this performance era often used limited pitch sets. Which explanation best fits the historical context?

• Composers preferred modal writing over tonal harmony

• Players avoided high notes to save endurance

• Natural brass relied on the harmonic series without valves

• Orchestras tuned to unequal temperaments routinely

Answer explanation

Natural brass instruments produce notes based on the harmonic series, limiting the available pitches. Without valves, players could only access specific harmonics, leading to the use of limited pitch sets in brass melodies.

In the Adagio introduction of Haydn’s Symphony No.104, what orchestral texture opens the fanfare-like motif?

• Brass choir only

• Woodwind trio texture

• Solo violin lines

• Unison tutti statements

Answer explanation

In the Adagio introduction of Haydn’s Symphony No.104, the fanfare-like motif is introduced with unison tutti statements, creating a powerful and cohesive sound that sets the stage for the orchestral texture.

Which harmonic device helps establish the minor mode early in the introduction?

• Augmented sixth chord

• Diminished tonic chord

• Neapolitan 6th chord

• Tonic and dominant pedals

Answer explanation

The Neapolitan 6th chord, built on the flattened second scale degree, effectively establishes the minor mode early in the introduction by creating a strong sense of tension that resolves to the tonic.

The omission of which scale degree in the first two bars creates modal ambiguity?

• The 3rd of the scale

• The 5th of the scale

• The 7th of the scale

• The 2nd of the scale

Answer explanation

The omission of the 3rd scale degree creates modal ambiguity because it is crucial for defining the mode. Without it, the tonality can shift between major and minor, leading to uncertainty in the harmonic context.

During bars 7–11 of the introduction, how does the harmony move before returning to D minor?

• Upward sequence through V of G, V of A

• Plagal motion to subdominant twice

• Direct dominant to tonic cadence

• Parallel minor to relative major shift

Answer explanation

The harmony moves upward through the dominant of G (D7) to the dominant of A (E7), creating a sequence that leads back to D minor, making 'Upward sequence through V of G, V of A' the correct choice.

Which statement best describes the quiet answering phrase in bar 3 of the introduction?

• Strings and bassoon create homophony

• Brass repeat the opening loudly

• Cellos present a solo countermelody

• Woodwinds imitate in octaves

Answer explanation

In bar 3, the strings and bassoon play together, creating a homophonic texture where the melody is supported by harmonies, making this choice the best description of the quiet answering phrase.

At bar 14–15 of the introduction, which progression prepares the cadence?

• Tritone substitution to deceptive cadence

• Secondary dominant to plagal cadence

• German sixth to perfect cadence

• Neapolitan 6th to imperfect cadence

Answer explanation

The Neapolitan 6th chord typically resolves to the dominant, leading to an imperfect cadence. This progression effectively prepares the cadence at bars 14-15, making it the correct choice.
