Midrash sur Cephania 2:14

(Fol. 48) "Since the Sanhedrin were abolished, with them was abolished the custom of singing [while in the wine-houses drinking], as it is said (Is. 24, 9) Amidst singing, etc." And whence do we know that this refers to the Sanhedrin? Said R. Huna, the son of R. Joshua: "The passage says (Lam. 5, 14) The elders have ceased from the gate, young men from their singing." R. Udna said: "He who listens to songs will at the end suffer punishment," Raba said: "In a house where there is frequent singing destruction will be the result, as it is said (Zef. 2, 14) Singing birds shall sing in the windows, ruin shall be on the threshholds; for the cedar waves shall be cut away. What does for the cedar waves shall be cut away, mean? Said R. Isaac, "Even a house covered with cedars will at the end be cut away." R. Assi said: "From this it may be inferred that ruin of a house begins with the threshold, as it is said, Ruins shall be on the threshold, and if you wish I shall say it may be inferred from the following: (Is. 24, 12) And in ruins is bitten the gate." R. Huna said: '"Singing while at work on a ship or while plowing is permitted, but otherwise is prohibited." R. Huna caused the abolition of singing, thereupon the market became so cheap that one hundred geese were bought for a Zuza and even for that amount there was no demand. Thereupon R. Chisda came and did not enforce the act of abolition when it came about that each goose was bought for a Zuza and even at that price there was not sufficient supply. R. Joseph said: "Men singing, and women responding is considered licentiousness. When women sing and men respond it is like flax placed before fire." What is the difference since both of them are prohibited? The difference is against which one we should put more efforts to have it abolished. Said R. Jochanan: "Whoever serves a banquet accompanied by four instruments of music, will bring five calamities upon the world, as it is said (Is. 5, 11) Woe unto those that get up early in the morning, that they may run for strong drink… . and the harp and the psaltry, the tabaret and the pipe, and wine are in their feasts. What is written after this (Ib., ib. 1.5) Therefore were My people lead unto exile, for want of knowledge, ie., this causes exile upon the world; and the honorable men suffer of famine, i.e., which brings hunger upon the world; and their multitude are panting with thirst, i.e., which causes the Torah to be forgotten from its learnings, (Ib., ib. 15) And then shall be the son of earth, and humble shall he the man, i.e., who caused lowering down to the enemies of the Holy One, praised be He, and the word Ish refers to the Lord as it is said (Ex. 15, 3) The Eternal is the Lord of war (Ish Milchama). (Is. 5, 15) And the eye of the lofty shall be hungry, who caused humbleness to Israel. What is written afterwards (Ib., ib. 14) Therefore hath the deep enlarged her desire, etc.
