The choir, but they had to stand on the floor and not on the duchan. Their shrill soprano voices often drew more admiration from spectators than those of the adults, to the chagrin of the latter.
To become an official member of the choir, a Levi had to train for at least five years. Once he became eligible, he might serve in this capacity until his voice was compromised by old age.
According to the passuk (Divrei Hayamim II 5:12), the choir members wore white linen uniforms. The duchan on which they stood was actually three steps leading up from the Ezras Yisrael to the Ezras Kohanim. Each step was half an amah higher than the surface below it. Anyone who entered the Azarah had to immerse in a mikveh first, and no one was permitted to sit down in the Azarah (kings descended from Dovid Hamelech were allowed).
The musical instruments used to accompany the singing were stored in leshachos (storage rooms) located just below the Azarah, and which opened to the Ezras nashim. These rooms also housed the textbooks from which the Leviim studied the methodology of their singing. The instruments were each enclosed in cloth covers and hung on the walls.
To be part of the Leviim choir, one had to study music and song for many hours each day and night, as the passuk tells us (Divrei Hayamim I 9:33). Because of this, the choir members were exempt from all other official duties in the Beis Hamikdash. According to the Chizkuni, those Leviim were not allowed to engage in any other pursuits lest their hands and fingers become calloused and unable to play the notes perfectly on their instruments. The Kuzari (2:64) likewise states that “they [Leviim] did not engage in any occupation other than music.... The originators and composers of this sublime art were Dovid and Shmuel.”
The Original Composers
Dovid and Shmuel lived before the first Beis Hamikdash was built, but they developed the system of the singing and music already in their times. They assigned the Leviim to their tasks, dividing their ranks into 24 mishmaros, each of which served in the Beis Hamikdash for a week at a time, and they trained them to perform. Dovid Hamelech chose members of the choir from those Leviim who had achieved the status of nevi’im. They were expected to be inspired to receive nevu’ah through their singing. In Divrei Hayamim I (23) we find that when Dovid Hamelech crowned his son Shlomo, he took a census of the Leviim. He found that 4,000 Leviim, were assigned to sing to Hashem and play the music that he had composed.
Why were the Leviim chosen for this exalted responsibility? The Sfas Emes (Likutim, Parashas Bamidbar) cites Chazal that when Moshe Rabbeinu grew up and saw how the Jews were enduring such terrible slave labor, he went out to assist whoever he could and lighten his burden. The Rebbe suggested that Moshe Rabbeinu was not the only one who did this. The entire tribe of Levi, exempt from slave labor, acted in much the same way, to one degree or another. In that merit, they were granted the honor of singing and playing music in the Beis Hamikdash.
Moreover, the Sfas Emes (Pesach 5641) pointed out that at the time of Yetzias Mitzrayim all of Bnei Yisrael were able to sing to Hashem, as they did at Krias Yam Suf. After the sin of the Golden Calf, however, this privilege was taken from them. It remained in the hands of Shevet Levi, who played no part in that sin.
Of course, these were no ordinary musicians. The tunes they composed were not simply a convenient way to express the pesukim in an enjoyable manner. Every musical note, high or low, staccato, allegro or adagio, signified deep kabbalistic concepts. The Shiltei Hagiborim (authored by 16th-century physician Avraham Portaleone) cites Rav Saadya Gaon explaining that the various titles on each mizmor of Tehillim signify the style of music to be played when it was sung. The tune simulated the desired message, be it one of joy, reflection, supplication, declaration and so forth. Rav Saadya Gaon identified a total of 22 distinct styles in Tehillim.
Each of the 12 requisite Leviim in the choir were expert in a particular type of singing. Sometimes the singing was divided into two groups of six who alternated between pesukim, and sometimes they were divided into three groups of four. The accompanying instruments were always in multiples of 12, corresponding to the 12 Leviim. For example, during the inauguration of the first Beis Hamikdash the choir consisted of 4,000 Leviim — four groups of 334 and eight groups of 333. And, as the passuk states (Divrei Hayamim I 5:12), they were accompanied by 120 Kohanim blowing trumpets.
