After doing research, I found that at Irish funerals and wakes specifically pick their music to convey the person and what they were remembered for. As in the wake scene you see in the move "P.S I Love You", you come to find out that the song playing in the background was one of the deceased ones favorite songs. Because this song reminded his family of him, they played it in his honor. JC Redmond asserts in his article "Music At Irish Funerals", that music and dance is seen during the wake and funeral ceremonies in a way to deal with grief (Redmond,2007). There for the music will usually be upbeat and lively and depending on the location at either the home or the funeral home, the music will vary. Redmond states that whatever music is chosen, it has to represent the live of the deceased one, and lyrics in which provide faith, and reassure their ability to see this person once again in the future (Redmond,2007). Another interesting musical tradition JC Redmond explained was the use of the bagpipe within Irish funerals. Bag Pipes were used "to tug at one's heartstrings when played at a funeral" (Redmond, 2007) Bag pipes are also seen within English, and Scottish funerals. There were many songs traditionally performed during funerals. Below is a link that shows a Bag Pipe version of Joyful, Joyful which is played in many Irish funerals today.

There is a commonality between these Irish funerals and ours throughout the lyrics of music. Though American music at funerals is somewhat depressing and solemn, they do provide hope for the future in seeing these loved ones again and explaining their importance during their lifetime. I hope to attend more funerals in America that obtain more lively music, and uplifting enviornments. If anything I would love my funeral to be celebrated with music just as the Irish use.
