There are no bad experiments when it comes to finding your voice. This is what you get when you speak in falsetto -- it's basically a falsetto voice. It's not actually creating tension around the entire larynx. I also recommend trying out funny voices -- all kinds, but especially the strange voices of animal cartoon characters. Try to mimic them as best you can. Just for practice.
Okay, here's another exercise. It's more about getting an idea of what happens when you do different things, kind of like building blocks can help to make a foundation. Spend a couple days working on your pitch, but not through reading words, just vocalizing vowels at higher and higher notes, up until just before your voice cracks -- which is the falsetto that we don't want, so once you know on what note your voice cracks, practice just below that because this isn't actually about making your voice crack. Anyways. Do it for the sounds of "ahh" and "eee" and "oh" and "ooo". When you do this exercise, feel your jaw and throat with your fingers. Feel where in your throat the sound resonates, but also figure out what muscles around your throat, around your jaw, and under your chin are being activated. 10 minutes a day.
Second, consider how your tongue gets engaged with speaking the following words in order: "YE -- YAY -- YO -- YOU -- YAH -- YES". Say those words in varying pitch over and over again, for like 10 minutes every day as part of your regular pitch practice, and do each word in a different pitch, up or down, it doesn't matter, just so no two consecutive words have the same pitch. We are doing this to strengthen the tongue muscles.
Third, some aftercare. When you're done practicing, do a salt water gargle -- a quarter-teaspoon of salt for 8 ounces of water. Gargle just a mouthful at a time, and be careful not to swallow! One to two minutes of this. Voice practice can lead to swelling in your throat, and a salt-water gargles helps to ameliorate that.
Finally, whenever you're swallowing regular water or food, I want you to feel your throat muscles with your fingers. Feel the sides, feel the adam's apple, feel the top and bottom, and again between your jaw and under your chin, just become familiar with all the complicated stuff that's going on there.
And keep up the good work.
