Hallelujah...This psalm has 13 praises (using the root h-l-l), a hint of God's 13 Attributes.
MISHNA: One does not recite fewer than ten verses in theblessing of Kingship, or fewer than ten verses in the blessing of Remembrances, or fewer than ten verses in the blessing of Shofarot. Rabbi Yoḥanan ben Nuri says: If one recited three from each of them, he has fulfilled his obligation.
Lute and pipe...these are various instruments.
Lute and pipe...instruments that we don't know.
All...And on all these praises, it is the praise of the soul as it contemplates the works of the Blessed God. And it is with the recognition that this is based on the strength of the soul while it is in the body, and so it says to the souls, 'Praise God!'
On a related topic, the Gemara cites that Rav Yehuda said: One who goes out during Nisan and sees trees that are blossoming recites: Blessed…who has withheld nothing from His world, and has created in it beautiful creatures and trees for human beings to enjoy. Rav Zutra bar Toviya said that Rav said: From where is it derived that one recites a blessing over scent? As it is stated: “Let every soul praise the Lord” (Psalms 150:6). He explains the verse: What is it from which the soul derives benefit and the body does not derive benefit from it? You must say: That is scent. Even over items from which only the soul derives benefit, one must recite a blessing and praise God.
