No. That's a fan-series called "Cure Queentet!".

Copied from zerochan:

"Cure Queentet!" is a CD-ROM released on October 28, 2012 and produced by fans, for which six new Pretty Cures were created by Imahia imitating the art style of Umakoshi Yoshihiko. It contains 34 original tracks. Each girl represents a musical instrument and, to restore peace, the Cures have to collect the Steinberg Keys. An anime version doesn't exist.
