If you are asked to play a song of which you don't know the chords you can play it instanly if you know the key of the song and if you have a little trained ear.So I thought it will be useful to post key signatures of Sinhala Songs.Once you know the key signature you can try to identify the chords being played in the song.It will be a good ear training exercise.
But Don't worry I'm not going to stop posting chords of Sinhala songs :)
Here is a list of songs by Athma Liyanage ,I have already posted the
chords of Liyathambara Song.If you need the full set of chords of any song,Please make a request using facebook or blogger comment system,I will try to complete the requests as soon as possible
