It would not hurt to try. Using your phone to record your singing may not be the best idea, the microphone is so small that singing even with normal volume gets the recording easily distorted.
USB-connected microphones are pretty cheap and will perform much better, just hook one to a laptop and use any simple recording software.
And I recommend starting small with children’s songs. “Twinkle Twinkle Little Star” with it’s straightforward ascending and descending melody is a great starter, or at least for me it was.
I visited a museum where there you could handle exact replicas of the swords and maces they had on display. The edges were blunt and the short chains they were attached to were bolted to the stone floor, so no one could steal them or do any damage with them.
But if you knelt down, you could get the feel of wielding them in action. One handed sword was really light and even my then 13-year old son could handle the two handed one.
I had read that they weren’t heavy, but I was still very surprised how light they actually were.
