Psalms 92:2
טוֹב לְהֹדוֹת לַה' וּלְזַמֵּר לְשִׁמְךָ עֶלְיוֹן
It is good to give thanks to Hashem and to sing praises to Your Name, the Most High.
This is the start of the “Song for the Sabbath day.” What’s the connection between Shabbos and praising G-d? The Radak explains that Shabbos is the best time to thank G-d because we are freed of our usual worldly distractions. On Shabbos, our souls are unencumbered by the mundane things that typically weigh us down, enabling us to praise G-d with much greater focus.
