The note A♯ has the same sound as which other note?

A
B♭
G♯
B

B♭

The note A♯ has the same sound as the note B♭.

To determine which note has the same sound as A♯, we need to understand the concept of enharmonic equivalents. Enharmonic equivalents are different notations for the same pitch.

The note A♯ can be found by moving one semitone (half step) higher from A. Now, let's look at the options:

- A: Moving one semitone higher from A gives us A♯, so A is not the correct answer.
- B♭: Moving one semitone lower from B gives us B♭. Since A♯ and B♭ are enharmonic equivalents, B♭ has the same sound as A♯, so B♭ is the correct answer.
- G♯: Moving one semitone higher from G gives us G♯. Since A♯ and G♯ are not the same note, G♯ does not have the same sound as A♯, so G♯ is not the correct answer.
- B: As mentioned earlier, moving one semitone higher from A gives us A♯, not B. Therefore, B does not have the same sound as A♯, so B is not the correct answer.

In conclusion, the note B♭ has the same sound as A♯.
