Question

there is a musical notation with a treble clef and a sharp symbol, and below it a piano - like keyboard with some keys colored red (c#, c, d, e, f#, f, bb) and others white (g, a, b, cb, db, eb, gb, ab). the text \__ major\ is present, asking to identify the major key based on the given musical notation and keyboard layout.

Explanation:

The key signature has two sharps (F# and C#), which corresponds to D Major (since D Major has a key signature of two sharps: F# and C#). Also, the red - colored notes (C, D, E, F, F#, C#) align with the notes in the D Major scale (D, E, F#, G, A, B, C#; the red notes here include the relevant scale degrees and the sharps).

Answer:

D
