A triad that contains the notes A and C could also contain the notes F or E.
To determine the correct answer, we need to understand what a triad is and how it is formed.
A triad is a chord consisting of three notes that are stacked in thirds. In the case of a triad that contains the notes A and C, we have a root note (A) and a third note (C).
To find the other note that can be included in this triad, we need to determine which notes are a third interval above A. In music theory, a third interval consists of skipping one note in between.
Starting from A, we count up the musical alphabet: A, B, C. So the note C is a third interval above A.
Now, let's consider the given options:
- Option (1): F - Starting from A and counting up by thirds would be A, B, C, D, E, F. F is not a third above A, so it does not fit.
- Option (2): B - Starting from A and counting up by thirds would be A, B, C. B is indeed a third above A, so it is a valid answer.
- Option (3): E - Starting from A and counting up by thirds would be A, B, C, D, E. E is also a third above A, so it is a valid answer.
Therefore, the correct answer is (2) B and (3) E. A triad that contains the notes A and C could also contain the notes B and E.
