Question restatement: Based on the MAJOR key signature, what is the harmonic function of the given note? Options to consider: tonic, supertonic, mediant, subdominant, dominant, submediant, leading-tone.

Option 1 – tonic: If the note shown aligns with the tonic pitch of the MAJOR key indicated by the signature (for example, in a key with two sharps, F# and C#, the tonic for D major is D), this pitch functions as the tonal center or tonic. The tonic is the chord I, providing the sense of rest and completion within the key.

Option 2 – supertonic: The supertonic is scale degree 2, built on the second note of the major scale. In a major key with two sharps (D major), the supertonic would be E. If the given note is not E or does not establish tension toward the dominant, this option would be incorrect.

Option 3 – mediant: The mediant is scale degree 3 (F# in D major). It typically functions as a coloristic or part of progressions that move between tonic and other chords, but by itself it does not establish the tonic function.

Option 4 – subdominant: The subdominant is scale degree 4 (G in D major). It tends to lead away from the tonic and toward the dominant, creating a sense of departure rather than the home base of the key.

Option 5 – dominant: The dominant is scale degree 5 (A in D major). It creates strong tension and seeks resolution back to the tonic; however, the note alone as presented should be evaluated for whether it serves as the root or leading tone of a V harmony. If the note is not the dominant pitch or not functioning as a dominant harmony, this would be incorrect.

Option 6 – submediant: The submediant is scale degree 6 (B in D major). It does not provide the primary sense of home or tension-resolution typical of a tonic or dominant function.

Option 7 – leading-tone: The leading-tone is scale degree 7 (C# in D major). It has a strong pull to the tonic but typically appears as part of a dominant seventh or V7–I preparation. On its own, the note may imply a leading-tone function only if part of a dominant function, so isolated appearance may mislead if not resolved toward the tonic.

Putting it together, since the provided answer in the data is tonic, the analysis aligns best with the note acting as the tonal center within the major key signature shown. The other options describe neighboring functional roles that either move away from the home pitch (subdominant, mediant, supertonic, submediant) or describe a tension-bearing role that typically requires context (dominant, leading-tone). The key factor is whether the given note corresponds to the tonic pitch for the major key indicated by the signature, which would validate a tonic function. If the note does not align with the actual tonic pitch, then one of the other functions would be more appropriate.

Note on potential ambiguities: Without explicit knowledge of the exact key (beyond “MAJOR key signature” in the prompt) and the absolute pitch of the shown note, the precise assignment could vary. In many common MAJOR-key contexts with two sharps, the tonic is the note that serves as the home base (I) of the key (for example, D in D major). If the visual note aligns with that tonic pitch, your choice of tonic is correct; otherwise, reinterpretation against the actual tonic pitch of the key would be needed.
