Friendship is the true magic!
Aisha and Stella work together as the Winx defeat the Treants, and earn their new Bloomix Powers. Later, the Winx and Daphne tour the Golden Auditorium where they come face to face with a group of not-so-melodic sprites!
While Daphne brings her class to visit the Golden Auditorium, Selina unleashes the screaming Pandemonium Sprites upon the prestigious music college.
Stella drags Aisha away from one of the Flying Basilisk's petrifying rays. Looking back at the petrified Roy and Nex, Aisha promises that she will return and save them. Aisha and Stella continue their escape, although the Basilisk is not far behind. The battle rages on as the Paladins and the Specialists fight the beasts. The Winx try to run to safety, while the witches attack the fairies. Musa and Tecna flee together, and to distract the monster, Musa blasts a magic spell on the beast’s head, which creates headphones with disturbing music.
Stella and Aisha stop for a while to see what’s going on. After seeing the horrible status, Aisha suggests that they do a triple back flip to set a trap on the Basilisks. The trick causes two of the beasts to petrify in the air after accidentally staring at each other. Aisha and Stella safely land, while the statues of the beasts break apart.
After saving lives by reducing the amount of Basilisks, Stella and Aisha gain their Bloomix. Stella uses a special Bloomix spell, which returns the allies to normal and destroys the beasts. Meanwhile, a group of witches surround Flora, but she defeats them for the moment. Meanwhile outside Cloud Tower, Bloom and the Trix fought fiercely. However, Bloom tells them that Cloud Tower is moving away. Aisha, Stella, and Flora meet up with Bloom and team up. The Trix leave, but they send lightning bolts to attack the Winx. Aisha forms a shield to protect the Winx.
The students of Linphea College celebrate and thank the Winx, Specialists and Paladins. Flora and Miele rejoin and hug, with Flora congratulating and encouraging her little sister. At the end, Miele wipes a way a tear of joy.
The Winx and the students are back at Alfea, waiting for Daphne to arrive. Stella gives the Winx new hats which are inspired by the battle.
Daphne comes in late, but excitedly tells everyone that she and her whole class have been invited to the Golden Auditorium. Musa reads the invitation excitedly, stating that the Golden Auditorium is the most exclusive music college in the whole Magic Dimension, so Daphne explains everything about the trip.
In her room, Musa calls Riven, who is practicing by himself. He, however, does not sound as excited as Musa, so she reminds him that she had always talked about it with him. Riven still does not care and continues his training, not even looking back once. Musa wipes her tears and says goodbye to him. Depressed and sad, Musa asks Tecna what she thinks. Ignored, Musa just talks to herself sadly. To cheer herself up, she plays her guitar, in which Tecna says to play it later. They begin to fight, and Bloom walks in to their room asking what is going on and that she has never seen them this way. Musa and Tecna complain to Bloom, who indirectly advises them to stop. Musa says that at least going to the Golden Auditorium will cheer her up.
The next morning, the class are on a trip to the Golden Auditorium. Musa explains what the statues are, so Daphne compliments her. A few moments later, Daphne greets an old friend of hers, Diletta, who is the headmistress of the school. The Winx and Diletta introduce themselves. Diletta asks Daphne if they may speak privately. Daphne allows the Winx to explore, then she walks with Diletta to discuss the attack of the Trix on Linphea College.
At Cloud tower, the Trix complain about the Winx, then went to their next destination, leaving Selina with her Legendarium. A mysterious man named Acheron, who seems to be Selina's boss, warns her.
Back in the Golden Auditorium’s hall, the Winx observe a girl playing violin. The pixies invite Stella to see a piano. Musa explains that the piano is the Golden Grand Piano of the Meller Explories. Stella plays it, and Musa added that every note produces a spring color. Aisha plays a magical violin, and the others looks at the rest of the instruments.
Musa begins to explain about the legend that states that deep underground there is a cave system, where mischievous, magical creatures whose loud shrieks can break hundreds of glasses called the Pandemonium Sprites lived, which Tecna says that it is an alleged legend. Meanwhile, Selina summons the Sprites using her Legendarium.
Musa and Tecna start to argue while Caramel plays the piano and accidentally jumps into a tube. The Pixies get in too to help her, and they blast out of it. The Winx and pixies laugh, but suddenly the Pandemonium Sprites begin to attack. Upon hearing the dangerous sounds, the Winx, except for Musa and Tecna, transform.
The Sprites and the Winx fight, but their screeches are stronger than them. Musa and Tecna try to get away from the attacks. To lead the beasts away, Musa plays music from her flute. In a long path, Musa, Tecna and the pixies still escape from them, but Tecna detects a location underground - the Pandemonium Cave and said that they need to lead the Sprites to the nearby cave. The two friends and the pixies arrive, and the beasts finally enter and corner them. Musa suggests using her own voice to overpower the Sprites’ sound. Musa sings beautifully, and the creatures admire her voice. Musa manages to form a shield around her friends. After that, Tecna and Musa hug, and congratulate each other, earning them their Bloomix powers.
By combining their powers, Tecna and Musa manage to eliminate the Sprites. At the end, Diletta congratulates and thanks the Winx and says that their composition will forever echo in their hall. Daphne is amazed and compliments them. Musa and Tecna argue softly with happiness, so the Winx and the Golden Auditorium students laugh and cheer.
At Alfea, Bloom sees that Tecna and Musa are getting along again. Bloom giggles and closes the door.

- With Musa without her powers, it is noticed that she can still create magic. This may mean that with a drop of the Dragon's Flame power, the Winx can still create simple magic regarding their main magic abilities. For example, Musa can use simple magic based on music (headphones, flutes, etc). However, for Stella, she is not able to make clothes appear even with the Dragon's Flame, due to the reason that she is the fairy of the Shining Sun (and the moon), and not a fairy of Fashion.
- It may also be that Musa's flute is magic and Musa was using the magic of the flute.
- Musa plays the flute and uses its music to lead the Pandemonium Sprites to the Pandemonium Cave. This is a reference to the legend of the Pied Piper of Hamelin, who used his magic pipe to lure rats and later children from the town of Hamelin in Germany during the Middle Ages.
