From falsetto to full range, Dinah Jane of Fifth Harmony packs a vocal punch, and has proven she can hit notes just as aggressively as she hits the band's expertly choreographed dance steps.

Since 2012 and her career's introduction on X Factor, the 19-year-old performer has spilled over with confidence, and given a powerful edge to 5H's expanding catalog. Dinah Jane's mix of strength and vulnerability has made tracks like "Leave My Heart Out of This" and "Better Together" standouts — you can see clear evidence in the collection of standout sets above.

And DJ has demonstrated she can hang with the best of her pop contemporaries, too — she's covered everything from Mariah Carey's "Emotions" to Drake's "Hotline Bling" and even Leona Lewis' "Bleeding Love" without batting an eye.

While 5H show no signs of stopping — their new "Down" is already catching on — Dinah Jane has already racked up an impressive collection of vocal moments. Check 'em out, and tell us if there's a performance that left you particularly stunned.
