How is the 3/4’ played?

Hi Dave,

After a year off from my harmonica studies due to a job change, I’m back at it and working on the level 4 Tremolo and Vibrato lesson.  In example #2, at the end of the first line is a triplet 4  3/4’  3’.   How is the 3/4’ played?  I’m assuming it is the 3 and 4 played together with 4 bent ½ step but the 3 won’t bend that much as it requires a larger oral area to bend?  The triplet is played quickly enough that I can’t tell what you are doing in your recording, even when I slow it down, I’m not hearing 2 notes played together.

Thank you,
