Reddit mentions of Músculos intrínsecos da laringe e dinâmica vocal (Portuguese Edition)

If you have problem to singing louder i would recomend you to use a microfone. Because singing louder gonna damage your vocal fold and your ear (Hearing loss).

But if microfone is not possible, I recommend do semi-occluded vocal tract exercises (SOVTs) to strengh your vocal tract, and about falsetto, you need to know which pitch are you gonna sing to know which muscle are you wanna train. Basics is: C4 to C5 (piano) you gonna use Thyroarytenoid, anterior cricoarytenoid muscles and interarytenoid, in primary sinergy. Below: E4 to B3 (piano) cricoarytenoid muscles.

Also remember about strengh exercise: isometric, isotonic and isokinetic

Isometric: hold pitch / Isotonic: one note up and Down / Isokinetic: vocalize

And vibrato is training, just train everyday


I recommend you read: Silvia Pinho's books (https://www.amazon.com.br/M%C3%BAsculos-intr%C3%ADnsecos-laringe-din%C3%A2mica-vocal-ebook/dp/B07Q46KBKV?tag=goog0ef-20&smid=A18CNA8NWQSYHH&ascsubtag=go_1686871380_65779544836_327582895583_pla-579888887987_c_)
