For those who hold sefira from the first day until the thirty-third, are the restrictions in effect during chol hamoed? While you are not allowed to cut your hair even during chol hamoed Succos, can one listen to music during chol hamoed?
Aruch Hashulchan 493:4 cites, if I'm reading him right, "various customs about [the restrictions of these days]. Some have practiced a prohibition from immediately after Pesach until the 33d of the omer and from then on weddings and haircuts are permitted, because a midrash has it that fifteen days before Shavuos [the students of Rabi Akiva] stopped dying, so that 34 days are left; it would have been logical to practice the prohibition until the 35th of the count, but we say part of the day is like its whole, so [these things are] permitted on the day of the 34th and not earlier.... [And others keep the second 'half'.]" (Emphasis added.)
As always, for a matter of practical halacha, CYLOR.
Pri Megadim (Mishbitzos Zahav) Siman 493 S"K 2 writes based on the Magen Avraham that one should stop already by Chol Hamoed: "ריקודן ומחולות יש לאסור בחול המועד פסח"
