What note completes the major triad with the root F?

The note that completes the major triad with the root F is A.

To complete the major triad with the root F, you need to add the other two notes that make up the triad.

A major triad consists of three notes: the root (F in this case), the major third, and the perfect fifth.

To find the major third above the root F, you count up four semitones (half steps). From F, counting up four semitones gives you the note A.

To find the perfect fifth above the root F, you count up seven semitones. From F, counting up seven semitones gives you the note C.

So, the major triad with the root F consists of the notes F, A, and C.

To determine the note that completes the major triad with the root F, we need to understand how major triads are formed. A major triad consists of three notes: the root note, a major third above the root, and a perfect fifth above the root.

In the case of an F major triad, the root note is F. To find the note that is a major third above F, we need to count four semitones (also called half steps) above F. Each piano key, including the black keys, represents one semitone or half step.

Starting from F, we count up four semitones: F#, G, G#, A. Therefore, the note that is a major third above F is A.

Next, we need to find the note that is a perfect fifth above F. To do that, we count seven semitones above F: F#, G, G#, A, A#, B, C, C#. Therefore, the note that is a perfect fifth above F is C.

To summarize, the F major triad consists of the notes F (root), A (major third), and C (perfect fifth).
