Modulation

A melody that modulates to its dominant key specifically often introduces the

• A.exact same key signature as the original tonic key, with no change of any kind
• B.raised seventh degree (leading note) of that new key
• C.lowered third degree of the new key, a feature instead associated with a minor key
• D.a factor entirely unrelated to introducing the raised seventh degree of the new key

A melody in D major modulating to its subdominant key specifically would modulate to

• A.A major, a key that would instead represent modulation to the dominant, not the subdominant
• B.G major
• C.B minor, a key that is instead the relative minor of D major, not its subdominant
• D.a factor entirely unrelated to modulating to G major from the key of D major

A melody that modulates to its subdominant key specifically often introduces a new,

• A.a factor entirely unrelated to introducing a new flattened note
• B.raised seventh degree, a feature instead typically introduced by modulation to the dominant
• C.flattened note not found in the original tonic key
• D.sharpened note not found in the original tonic key, the reverse of the typical change
