Have you ever wondered if you are singing Irish songs the right way? The definition of traditional Irish music is basically something that has been passed down through the generations using nothing but word of mouth. The best and easiest way of singing Irish songs is by hearing others while they sing and then copy it from there.
The same songs might even use a variety of different words based on who is recording it. You should learn the version that you like the best. Hear the structure, envision its reasoning, etc. There’s an art for learning by ear & understanding how tunes work. You need to get a feeling for the song. Abandoning sheet music can be quite intimidating for music students and figuring out the structure of tunes using your own talents may not be the easiest thing in the world either.
Irish songs can easily be sung by simply reading notes and then hitting all the right ones with surgical precision. But even then the feeling is still going to be off. Learning how to sing Irish songs with the help of sheet music is similar to trying to use a road map to find your way around malls. You will have to be quite careful and shouldn’t imitate too much.
A lot will depend on the accent that is being used as well. If you aren’t singing with an Irish accent, chances are the song is not going to sound the same no matter what you do. You could try singing with an Irish accent, but it is probably is not going to work. Just as long as you are giving it your all, though, not many people are going to hold anything against you. So don’t worry about being perfect all the time and just let her rip.
