There are many questions I have regarding the Halachos and customs for Ashkenazim during the nine days.
The first question I have is regarding showering. During the nine days one is supposed to refrain from bathing and showering because this is considered something relaxing. In the current times would it be acceptable in society if people found out you did not shower for 9 days? I am not sure what most people do in regards to this. I have heard two things where you can get around this Halacha. The first one is to only take cold showers. By taking a cold shower you are not enjoying it doing it only for hygiene. The second way around this is to build up a sweat (working out in a gym) so you would smell which would allow you to shower.
The second question I have is regarding Neginah and music. During the three week period beginning with the 17 of Tammuz and ending on the 10th of Av, one should not listen to music. I can understand this completely because we are supposed to be mourning and music can make someone happy. My question is regarding Shabbos and niggunim which are sung on Shabbos Chazon. It is the custom of many shuls to sing Lcha Dodi to the tune of Keli Tzion which is the last Kinna we recite in the morning of Tisha Bav. If we are supposed to be happy on Shabbos we should not remind ourselves of the nine day mourning period, correct? If so why is that niggun sung to Lcha Dodi? Last year I went to an Agudah minyan which I knew would not sing this niggun for Lcha Dodi. The question can then be asked, every Shabbos Chazon, the Haftorah is read in Eicha trup as well as the word Eicha which appears in the Parshah. I am not sure if every shul does this or only the ones I have been to. Where did these customs come from, and why are we allowed to be mourning on this Shabbos? Are these customs wrong or are they correct? With these questions in mind, I am not sure where to daven this year.
