Bb7sus2 (Guitar, Beginner)

Bb7sus2, or B-flat 7th suspended-2nd, would be a good candidate for some intermediate-skill level chord analysis, but here's the beginner rundown:

1. Using the length of your index finger, make a bar from the A string to the High E string, behind the 1st fret (Bb, Ab, C, and F notes).
2. Your middle finger will not be used for this voicing.
3. Place your ring finger on the D string, behind the 3rd fret (F note).
4. Avoiding the Low E string, strum the Bb7sus2 chord.
