Hi, If you would prefer to sing......even better......, why not use a tape recorder and tape yourself and then listen after. Notice if you are singing on key
and holding the note. If someone works at it, inside of a few weeks, they will sing at least more accurately. A " supposedly good" singer that is off key, flat etc is not as good as an amateur that can hit his (or her) notes.
And don't go for super stylized music right away. Learn to sing it clean first.
When you get it pure first, you will keep something of that once you intonate a style. And remember: Volume ....too much of it is like bad beer. A little of the better stuff is enjoyed and remembered.
I hear some amateurs that play OK and would sound better if they turned it down, ....so you can hear an unstrained melody, a voice that is comfortable
and not competing with the music but complementing it.

Thanks Titana, Best regards from sunil,

I think karaoke is quite popular technique to enhance the musical and singing ability of one, the links you joined here are quite informative. I think one can plug in, in the option of "recording the voice", may be sing directly while posting the material, because someone if they like to engage fully "to receive the utmost concentration", they can sing and type at a time on the computer. But when I use this option of "recording the voice", the voice quality was received not so much good. I heard previously that one doctor in mumbai doing the operation of a patient by "singing and hearing the music", their experience is quite nice in this regard, I am fail to recall their name and their website, but just I heard from one of my relative in mumbai (India).

I think in the old times when man was alone in the forests later they search this practice to "sing", I don't know the details of "evolution of singing".

I like singing, but I tried in marathi language (this is called as "Marathi Bhakti Sangeet" A spiritual marathi songs, because I came from a very spiritual and typical maharashtrian Marathi Brahmin family). Many of my church friends told me that sunil you can sing english songs, I said them I have a problem in "keeping a whole english song in mind", they told later that use a english tape recorder and a headphone, listen the song and sing the same, I tried and I succeed to sing one well song " Oh my sunshine". Because on it my sister was made "clapping".
