Արևմտահայերեն

This is an Armenian lullaby. It's traditional in Armenia for their lullabies and children's songs to be about the Armenian genocide, as mentioned here: https://en.m.wikipedia.org/wiki/Lullabies_of_Armenia

Unfortunately my Armenian isn't quite good enough yet to translate to English, but the title means "Come, my Nightingale" according to the wiki page.

The symbol that looks like this in the original text: ՛
This is called a sesht, it is used on the last vowel of a word to mark emphasis or exclamation

Kh = hard ch like German loch
Any letter with an apostrophe after it is more strongly aspirated (k' is typically transliterated as q)
Gh = guttural sound like German or French r
Rr = more strongly rolled than regular r
Ë = schwa, sometimes not pronounced
