Here is a commonly played F13 chord shape. The full F13 chord would theoretically contain the notes: F, A, C, Eb, G, Bb, and D. However, when playing on a guitar, we often have to omit some notes while ensuring the chord still retains its characteristic sound.
For an F13 chord using only the 6th, 4th, 3rd, and 2nd strings, focus on the essential tones: the root (F), the third (A), the dominant seventh (E flat), and the thirteenth (D).
