Shabbat Halacha Guide: Door Chimes, Music, Clapping & Everyday Scenarios Explained

1. If small bells are installed on the entrance door and ring whenever someone enters, is it permitted to go through that door on Shabbat?

Ideally, they should be removed before Shabbat, since there is a halachic dispute, as explained in the Mishnah Berurah (siman 338:6), due to a concern of the rabbinic prohibition of “producing sound.”

However, if they were not removed, one may be lenient in a pressing situation, following the opinion of the Magen Avraham, since the person entering does not intend to produce the sound.

2. If a child turned on music in the house on Shabbat, what can be done to reduce the noise?

The preferred solution is to place blankets or similar coverings over the speakers to muffle the sound.

If the noise is still audible, the ruling depends on how the volume is controlled:

• Mechanical volume control: It is permitted to lower the volume, since no new electrical current is created. Although the knob is considered a “utensil primarily used for prohibited activity” (kli shemelachto le’issur), it may be moved for a permitted need (siman 308:3). It is preferable to do so in an unusual manner.

• Digital volume control (e.g., changing numbers or bars): It is permitted to lower the volume only in an unusual manner, since this involves a double rabbinic concern:

1. The “writing” is not permanent.

2. The action is performed in an unusual manner.
   In cases of significant need, leniency is allowed (as discussed in the Magen Avraham, siman 307).

However, one should not unplug the device, even with a change, because this involves breaking an electrical circuit, which is considered a serious prohibition according to the Avraham Yeshaya Karelitz. Therefore, lowering the volume (with a change when necessary) is preferable.

3. If a synagogue attendee dances, claps, or taps on the table in rhythm during Lecha Dodi or similar parts of the service, is this permitted?

• Dancing and clapping: These are rabbinically prohibited, and one should point this out to the person. However, if it is clear that he will not listen, one should not rebuke him, following the principle: “It is better that they remain unintentional sinners rather than intentional ones.” (Shulchan Aruch siman 339:3; 608:2).
  This applies to Sephardim. For Ashkenazim, those who are lenient have authorities to rely on (Rema), though the Mishnah Berurah adds that leniency should only be relied upon for the sake of a mitzvah.

• Tapping on a table in rhythm: This is prohibited and should not be permitted under any circumstances (Mishnah Berurah).

4. In a synagogue where the cantor taps on the bimah in rhythm during Kabbalat Shabbat, is this permitted? And may one participate in such a prayer?

Tapping in rhythm is prohibited on Shabbat (Shulchan Aruch siman 339:3). One should gently inform the cantor and show him the halacha.

If he does not listen, it is preferable to pray elsewhere. If that is not possible, one may still pray there, as long as he does not focus on the tapping and is not assisting in the prohibition (unless he is needed to complete the minyan).

5. Is it permitted to tap on a table in rhythm while singing on Shabbat?

Clapping on Shabbat is prohibited (Shulchan Aruch siman 339:3), but if done with a change, it is permitted.

Therefore, tapping on a table may also be permitted if done with a change, such as using the back of the hand.

Among Ashkenazim, those who are lenient with clapping (even without a change) are not to be protested (Rema). However, regarding rhythmic tapping, one should not be lenient (Mishnah Berurah 339:10).
