Unfortunately, I am blind so I cannot see your diagram. It's best to use simple words or audio or video recordings with good description. Sorry for your trouble.
Sorry about that. I didn't know you were blind.
Here's a video tutorial on the olapa strum. A few words about the video first. The woman in the video uses the phrase "await for me" to describe cadence of the strum, but it doesn't account for the fact that there are two quick 16th note beats at the beginning. I would use a phrase more like "you can wait for me." with the words "you can" spoken really quickly as the first two 16th note bits of the strum. After she demonstrates the strum, there's a section that may not be helpful to you about holding the ukulele and playing the chords for the song she plays to demonstrate the strum. The song is in the key of C and the chords she plays are C, C7, D7, F, and G7, although she modulates at the end. Then she plays the song with her bass player husband, which should give you a good idea of the phrasing of the strum. As you listen, remember that olapa is a two beat strum that begins on the upbeat of the previous beat. It may help you to count the beats while you listen to see how the strum cycle (the "you can" part of the phrase) begins just before the first and third beats of the measure.
The woman in the video doesn't really describe the hand movements of the strum in as much detail as you might like, so following the video in this post, I try to describe in words the diagrams I made in my earlier post, using the phrase "you can wait for me." It may help as you listen to the video to repeat the phrase "you can wait for me" for each cycle of the strum.
One other tip. When I learn a strum, I find it useful to bank out the strum on the back of my ukulele first, to get a feel for its rhythm. It may help you to try that as you listen to the video.
So, here's the video.
I hope you enjoyed the video. Now that you've watched it, I try to describe the mechanics of playing the strum by translating the chart from my earlier post into words. I play this strum one of two ways:
1. This first version of the olapa strum uses my thumb and index finger. I start with my hand between the strings and the floor (on the A string side of the ukulele). For the "you can" part of the phrase, I flick my thumb up for "you" while leaving my fingers below the strings, bring my index finger up for "can", and then move my index finger down for "wait," up for "for" and down again for "me." My hand is then in position for me to flick my thumb up for the next "you." I needed to learn this strum by playing it very slowly for a long time.
2. This second version of the strum uses only my index finger. I start with my index finger between the strings and my face, on the G string side of the ukulele. For the "you can" part of the phrase, I move my index finger down and then up again. For the "wait for me" part of the phrase, I move my index finger down three times, once for each of the three words "wait for me."
In general, I prefer the first method, which is the strum that involves my thumb, because I don't have to move my hand so fast and my hand is more relaxed, allowing me to vary the stress I place on the strings each time I strum the strings and allowing me to be more expressive. However, it took me forever to learn how to flick my thumb up across the strings while leaving my index finger below the A string so it's in position to stroke upward for the word "can" in the phrase "you can wait for me."
I hope this helps.
