{Rosh haShana 34a continues}
{of Malchuyot, Zichronot and Shofarot} do not hold back the tekiot {from being fulfilled}, behold they have already fulfilled their obligation with those they blew when they were seated, and it is sufficient to blow tekiah shevarim teruah tekiah, tekiah shevarim tekiah, tekiah teruah tekiah on the order of the blessing one time so as not to burden the congregation. And so is the custom in the entire world and in the two yeshivot.

They asked before the Resh Mesivta: If one blessed on the day of Rosh haShana on the blowing of the Shofar after the sefer Torah {that is, those wihle seated} and he spoke {והשיח -- Bach emends to והסיח ודבר -- and he diverted his mind and he spoke}, does he needs to bless on the tekiot on the order of the blessings {of Malchuyot, Zichronot, Shofarot} or not?
And he responded to them as follows: The Sages see that we rebuke one who speaks before they blew on the order of the blessings; however, to repeat the blessings, he does not repeat. And it is not similar to tefillin which Rav Chisda said one who speaks between tefillah {shel rosh} and tefilla {shel yad} repeats the blessing, for these are two mitzvot, for they learnt {tnan}: The tefillah shel yad is not a prerequisite for the shel rosh and the shel rosh is not a prerequisite for the shel yad.
And not only that, but he does not bless the first blessing {of lehaniach tefillin}, but rather he blesses a different blessing {of al mitzvat tefillin}.
For we ask {there}: This implies that if he did spoke, yes; if he did not speak, no! But Rav Chiyya bar {Rav} Huna sent in the name of Rabbi Yochanan {from Eretz Yisrael to Bavel}: On the tefillah shel yad he says lehaniach tefillin and on the shel rosh he says al mitzvat tefillin.
And we resolve: Abaye and Rava both say that if he did not speak, he blesses one, and if he spoke he blesses two.
And even so, it is difficult {=not good} to speak, for they learnt {in a brayta}: If one spoke between tefillah {shel yad} and tefillah {shel rosh} it is a sin in his hand and he returns because of it from those arrayed in battle. And certainly one who speaks between the tekiot of sitting and the tekiot of standing; however, he does not repeat the blessing, for it is one mitzvah -- Go out and see, for behold, there is the Hallel upon which they bless before its reading, and even so, between one perek and the next perek, he may interrupt and is not required to repeat the blessing.

"If he blew the first tekiah {of the set} normally and extended the second one {tekiah, at the end of the set} like two, he only has one in hand {and must blow another tekiah for the beginning of the next set}":
