Hi,everyone! Im Aiden and im from Belarus (near Russia). I started singing 3 years ago.In 2016 my vocal range was F2-С4, so now its F2-C5,but... I can't go higher. The sound is near the ears and i think i still have space to go higher , but i dont have an idea how to do that (sometimes it pawns ears and i can hear myself like if i was in ear plugs. is it normal?). So for now my dream in singing is to reach G5 or even B5 . And with this question i came here looking for advice.
