good day , kind of silly question but does singing karaoke everyday is considered an effective way of improving singing ?

Great question! I think it'll certainly help improve your sense of timing and give you some performance experience. I'd recommend warming up your voice and working on songs as well. But I think karaoke sounds like a fun way to practice!

I warm up every day, then pick a song on spotify and do exercises to it. Then I google the lyrics and speak them out loud and decide which words consonants to emphasise, practice a bit and then go onto Smule and have a sing and when fairly happy join a duet for fun! I try to apply what I have learnt from 30 ay singer and sometimes focus on one aspect having seen lesson etc

That sounds like a great routine, Matt. Thank you for sharing!
