(Mishnah): The order of the Shofar blasts is three groups of three. The length of the Tekiyah is the same as three Teru'os. The length of the Teru'ah is three Yebavos (short sounds).

If he sounded a Tekiyah and continued the second Tekiyah (that follows the Teru'ah) as long as two Tekiyos (in order to be the first Tekiyah of the next set), he has only sounded one Tekiyah.

One who recited the nine blessings of Musaf and later received a Shofar, he should sound Tekiyah Teru'ah Tekiyah three times (to correspond to the three blessings of Musaf - Malchiyos, Zichronos and Shofaros).

Just as the leader is obligated to pray, so is each individual (and if they are able, they cannot rely on the leader's prayers to fulfill their obligation).

Rabban Gamliel: The leader can pray on behalf of everyone.

(Gemara): If he sounded a group of three Shofar blasts (e.g. Tekiyah, Teruah, Tekiyah) in one breath...

A Beraisa teaches that he has fulfilled his obligation.

Question: The Mishnah teaches that the order of the Shofar blasts is three groups of three - meaning that he should sound nine separate blasts, but if he sounds a group in one breath, he has not done this...?

Answer: The Mishnah is merely teaching that one should not sound less than this number of blasts.

R. Zeirah / R. Abba bar Ilay quoting Rav: He must sound a Tekiyah and a Teruah in the same breath.

R. Ba quoting Abba bar Rav Chuna: One need not sound a Tekiyah and a Teruah in the same breath.

Question: For how much time must a Teruah extend?

R. Chananya disagreed with R. Mana: One opinion said - like the (short) sounds of a trumpet. The other opinion said - it is the same as three sounds of any minimal length.

R. Chananya was stringent for R. Mana's explanation as well as his own explanation.

This statement (said in the 3rd Perek by R. Yosi that a person has certainly not fulfilled his obligation if he heard part of a Shofar sound from a Misasek - a person blowing without intent to fulfill the Mitzvah - since he did not hear the entire sound) was learned from the law of our Mishnah (see (b) above) that if a person sounded a set of blasts and continued the second Tekiyah (that follows the Teru'ah) as long as two Tekiyos (in order that it should be the first Tekiyah of the next set), he has only sounded one Tekiyah.

R. Abba bar Zemina quoting R. Zeirah: In such a case, he has not even sounded one blast.

Why is this? The beginning of one sound joins with the end of another and the end of one sound joins with the beginning of another. (However, the Halacha requires the entirety of each sound to be isolated.)

Question: If in one city they are sounding the Shofar (but there are no communal prayers) and in another city there are prayers (but they are not sounding the Shofar), to which city should a person go?

Beraisa #1: Go to the city with the Shofar-sounding.

Beraisa #2: Go to the city with the prayers.

Beraisa #1 applies when there will not be enough time to blow if he goes to hear the prayers.

Beraisa #2 applies when there will still be enough time to blow afterwards.

Question (R. Yaakov bar Idi quoting R. Yehoshua ben Levi): (We will prove that even if there is not enough time to go and hear the Shofar-blowing, one should still go and listen to the prayers.) If they are blowing in one place and praying in another, he should go to hear the Shofar rather than the prayers.

From where can we prove this? The Beraisa teaches - When Rosh Hashanah occurs on Shabbos, if they are blowing in one place and praying in another, he should go to the place where they are praying, but not to the place where they are blowing. Why is this? Since all know how to blow (and after he hears the prayers he will always be able to find someone to blow) but not all know how to pray.

Another reason - one can blow for someone (even without a quorum of 10 men) but one cannot recite the blessings for someone (without a quorum).

Conclusion of question: When Rosh Hashanah occurs on Shabbos, is it not like a day when there is not enough time to blow, and nevertheless, one goes to hear the blessings...?

This shows that it must disagree with the early statement.
