The creation of poetry is an internal process that bridges silent thought with fluent expression. The primary approach among commentators describes this initial inspiration as a subtle movement. It is compared to the gentle trembling of a person's lips lost in thought, or the slight rustling of a living creature [רש״י, רד״ק, מצודת ציון, מלבי״ם, מאירי, תורה תמימה]. The heart, acting as the center of intellect, thought, and prophecy, awakens and brings forth these ideas [רד״ק, אבן עזרא, מצודת דוד, מאירי]. Beneath the outer shell of this poetic expression lies a hidden, inner layer of exalted intellect and profound wisdom [מלבי״ם].
The focus then shifts to the song itself, which is the fruit of the poet's creation [אבן עזרא, ביאור שטיינזלץ]. This work is dedicated to a royal figure, though perspectives differ on his identity. Some suggest the song is dedicated to King David or the future King Messiah [אבן עזרא, מצודת דוד, מאירי]. A contrasting view reads the royal figure as an allegory for a Torah scholar, since sages are traditionally compared to kings [רש״י]. Building on this allegory, the text offers practical guidance on how a student should address a teacher. A student must prepare their thoughts carefully to ensure their language is clean and respectful, even if it requires speaking fluently and at length without taking shortcuts [חומת אנך].
Finally, the poet takes pride in his ability to express these thoughts, comparing his tongue to a scribe's quill [מצודת ציון, מלבי״ם]. This highlights a delivery marked by speed, expertise, and proficiency [רש״י, ביאור שטיינזלץ]. Just as a master scribe writes rapidly and without hesitation, the tongue produces clear, organized, and elegant poetry [רד״ק, מאירי, מצודת דוד]. Ultimately, the tongue acts as the pen of the heart. Like a skilled stenographer who copies every single word without omitting a detail, the tongue perfectly translates the stirring thoughts and emotions of the heart into a complete, precise poetic masterpiece [מלבי״ם].
