I guess I could eventually get higher and higher with the pitch while doing the scales and triads video. If I go up and down the same interval while doing the video, that would help overall. If I use the actual pitches in the video, that gives me the goal for each tone. It would be nice if that video showed the pitch for each tone.
I probably could get by with knowing the actual pitch for about the first few seconds of each sequence on the video, so I will start each sequence, if possible, at the right pitch. I cannot tell by ear if I match the pitch of the video as I sing the tones. If I sing at too low a pitch, that may not help, at least not until I get the pitch higher and higher over time, which is the goal. Measuring my evolving pitch with the tool you mentioned earlier would be good.
With that said, I will need to work on inflection and resonance also.
Thank you for your help, you are very thoughtful.
