In this video you will discover how to play an A chord on the piano:
The A Major Chord is made up of 3 notes: A, C#, and E.
To find the notes on the piano: Start with the C sharp- the C sharp is the lower note of the two black notes.
Put your right middle finger on that note. Your pinky goes on the white note above the group of two black notes to play E.
To find the A, count down 5 white notes (including the E) to get to A.
Put your thumb on A. Play the three notes at simultaneously, and you have played the A Major Chord.
