Is it obligatory to abstain from attending a wedding party that includes music to avoid sin, or to attend it to prevent the severance of kinship ties, given the option of sitting in a hall without disturbance?

If it is possible to attend an occasion where no music is heard, there is no harm in that. Scholars have permitted going to a place where there is an evil that is neither seen nor heard. However, if music will be heard, it is not permissible to go, and this is not considered severing ties of kinship. Kinship can be maintained by visiting the woman in her home.
