Praying with song

Hi,

"Rav Yehudah said, citing Shmuel: What is the essential source for music’s role in the avodah [the service in the Jerusalem Temple]?

"It is written, ‘And the priest will serve in the Name of HaShem, his Gd.’ Which type of service invokes Gd's Name? I’d say: Singing.

"Rav Matnah taught: It is written, ‘[You will be punished] because you did not serve HaShem your Gd with joy and with a good heart.’ What service is performed with joy and with a good heart? I would say: Singing."

(Talmud, Arachin 11a)

Have a great day,
Mordechai
