Shalom Aleichem.

My mother’s cousin composed this tune. It is one of the most famous tunes for Shalom Aleichem in the Ashkenazi world.

שָׁלוֹם עֲלֵיכֶם מַלְאֲכֵי הַשָּׁרֵת‏‏ מַלְאֲכֵי עֶלְיוֹן

בּוֹאֲכֶם לְשָׁלוֹם מַלְאֲכֵי הַשָּׁלוֹם מַלְאֲכֵי עֶלְיוֹן

בָּרְכוּנִי לְשָׁלוֹם מַלְאֲכֵי הַשָּׁלוֹם מַלְאָכֵי עֶלְיוֹן
מִמֶּלֶךְ מַלְכֵי הַמְּלָכִים הַקָּדוֹשׁ בָּרוּךְ הוּא

 
צֵאתְכֶם לְשָׁלוֹם מַלְאֲכֵי הַשָּׁלוֹם מַלְאָכֵי עֶלְיוֹן
