I started playing around with a tuner and the thing I realized is that when I go for the note, instead of hitting the note exactly, I tend to "search" for the note. I hit a note around ti and try to adjust.
I've been seeing what's up when I just play one note on the piano
For example if I play C, I might sing C# and then adjust downwards to C on my own, Instead of hitting the note immediately, I tend to slide to the note. Usually I'm noticing that I'm 0.25 cents off and find the note. If i get time to think about the note, I'm more accurate. But with singing a song, I'm forced to change so often that I keep finding myself in weird situations because I don't have time to adjust...again that's my ideas
I'll keep up with the Vocal exercises and Ear training. I've been working on that for the past few weeks
