In every bar, let your true self expose.

Chords of joy, harmonies of grace,

Navigate through time and space.

Let laughter be your rhythmic guide,

With every beat, let love reside.

Twenty-one keys on life's piano,

Play them all, in joy and woe.

Compose a song uniquely thine,

A melody that will forever shine.

Twenty-one springs, and you've come so far.

Twirl through moments, swift and slow,

In the dance of life, let your spirit glow.

Footsteps imprinted on the sands of time,

A journey of rhythm, sweet and sublime.

Chase dreams as the music plays,

Each note, a chapter in life's ballet.

Dance through sunsets, under moonlit skies,

Embrace the dance of sweet goodbyes.

Twenty-one spins, a pirouette in grace,

Welcome adulthood, in this sacred space.
