There were only so many times you could listen to something so terrible you feared your ears may not survive the experience, and choose to ignore the horror.
For Filius, the truth was that he could no longer listen to the school-wide rendition of the Hogwarts School song. He'd flinched and winced through too many of them, each more terrible than the last - the tears in his eyes each time weren't from reminiscing of his own school days, like the tears that clung to Albus' eyes.
He honestly didn't know who believed having everyone sing their own tunes was a good idea, but that person deserved to be tortured by a thousand banshees for the rest of their lives.
(It was Albus' fault. It was always Albus' fault.)
"Albus, I'm starting a choir to lead the school song," Filius stated. He wasn't going to take a refusal as an answer. Filius did not care what he would have to do to get the permission he needed, but he would involve Minerva if it came down to it.
"What a marvellous idea, Filius! I'll leave it to you to bring more joy to the walls of Hogwarts with music," Albus said, looking delighted. "I dare say even members of the staff may want to join."
Personally, Filius knew that he'd rather not have the staff participating, since he knew Albus would be the first to volunteer.
Having a single poster up on each of the Common Rooms' noticeboards was all it took to draw a group of fourteen to his office in the evening, in the hope of being a part of the choir. Most of them were Muggleborns who were part of their previous school's choir - and so had a better idea of what a choir was meant to be than he did - with only two Purebloods, whom had been dragged along with their Muggleborn friends, and a single half-blood Hufflepuff.
It was enough to start off with. A couple of Sonorus charms would boost the volume of their singing, and they could also bring in smaller creatures to assist with the sound if they had to later on.
Mutually agreeing to meet on Thursday evenings, after dinner, they had parted ways on that first night; the students with a sense of excitement, and Filius with a feeling is gratitude, that was coated in relief, towards his students.
They were willing to join him in trying something new. They weren't all First Years, but the majority were. Filius thought that after their initial run next year, he would have more people join the Choir - and eventually they could even make a little club of it.
He wouldn't need to listen to the horrid rendition of the Hogwarts song again; instead, he would be leading a delightful choir in a beautiful rendition of song. He would make sure the choir was ready to welcome the staff and students during the next Welcome Feast.
Failure was not an option.
