LET ME BRIEFLY TELL YOU HOW TO FIND THE KEY OF A SONG

Let me encourage u by tellin u dat u would get better at dis as time goes on
To find the key of a song,u must have a reference point,
This reference point depends on ur hearing ability.
Most songs start wit Doh and ends wit Doh
some especially minors start wit 'Lah and end wit Lah
keep dat in ur mind

A song like Baba,eshey oo baba eshey oo baba Awa dupe baba, It ends wit 'Doh' so wheneva they are singing dat song, sing it fast to the end and say the Doh out Loud, So you can hear ur self then find dat particular sound u said wit ur mouth on the piano,
If it happens dat the sound is on the key of F# then the key of the song is F#

What about a song that starts and end wit'Lah; Awesome God, is an example of such songs,
Awesome God, Mighty God we give u praise, awesome God you are highly lifted up awesome God
and so on and so forth,
The song end wit Lah, so whenever they are singing the song in the church,try to sing fast to the end and say the Lah
then find the sound u are singing out on the piano
Once u get the Doh of the song that wil be the key of the song
