Since the other party wanted Liang Liang to provide guidance, Liang Liang naturally wanted to test their basic skills to see if they were worth supporting.

He wouldn't waste his time if there was no value in supporting him.

Liang Liang could tell that these guys seemed somewhat unconvinced by him, but he didn't say anything.

Xiaoqian and Xiaoyao also ran to Liang Liang's side and sat down to pretend to be there.

"You can each perform a piece that you are familiar with first. You can choose the piece yourself."

Liang Liang and Liu Yuyong sat in front of the small stage in the dance hall, watching the four teenagers play instruments on stage.

After the four teenagers tuned their instruments to their own needs, they began to sing a recently popular rock song.

This is the signature song of a band called Leng Shuang, which has recently become quite popular in mainland China. The song is called "A Lifetime of Roaring".

This band and this song left no trace in my cool memories; they must be a band that doesn't exist in the original world.

"A Lifetime of Roar" is a psychedelic rock song with a small amount of heavy metal influence. The transitions in the middle are not very natural and feel a bit abrupt.

Just from the name, you can tell it's the kind of style popular in the rock scene—a style of melancholy, shouting, and anger.

Liang Liang had listened to this recently popular rock song several times.

After the four-minute-plus piece was finished, the four boys' eyes were fixed on Liangliang's face, waiting for her comments.

Liang Liang leaned back in his chair and pondered for a moment.

"After listening to your performance, I'd like to share my thoughts, starting with the lead singers one by one. The lead singer has a good voice; the high notes are smooth and resonant, with some depth. While not at an exceptional level, it's sufficient for most songs, making him a qualified lead singer for a band. However, your breathing technique is unscientific, and you're not using chest resonance effectively. If you don't change this, singing challenging songs will be very difficult, leading to uneven breath control, which will directly affect your performance."

Lead singer Yu Xiaolong did not comment on Liang Liang's evaluation because Liang Liang was telling the truth.

"Now let's talk about your guitar. Your guitar skills are very proficient, which shows that you have spent a lot of time and effort on the guitar. However, I feel that you seem to know nothing about music theory. To put it simply, you just play the guitar randomly."

Yu Xiaolong didn't like hearing this and retorted on the spot: "I can understand the concept of 12-tone equal temperament chords very well."

"That's right! I can hear it, but once you get into the concept of pitch, don't you feel confused and disoriented?"

Yu Xiaolong was speechless; he did indeed feel the tone was chaotic at times.

"Actually, this is normal. To fully understand the concept of mode and tonality, you need to read more books. For people at your stage, I don't recommend using scale exercises to fully understand the key. It's not too late to practice after you've learned cadenzas and can memorize the scale distribution diagrams of the 12 keys."

"Then how can I master it as quickly as possible?"

"You can learn about keys by switching between C major and G major. You must remember the meaning of the six basic chords in C major and G major. Once you have memorized them, play some simple songs you have practiced in C major and G major, alternating between the two. When you learn a new key, switch the C major and G major you have learned to the new key. Over time, you will master it."

Yu Xiaolong didn't seem to quite understand.

"Wow! Brother Liang, your serious demeanor is so charming, I'm totally smitten!" Xiao Yao exclaimed at this moment.

You can just say I'm showing off, that's all.

However, Liang Liang ignored her and his gaze had already shifted to the bassist.

"I'm a bassist myself, so I'm particularly sensitive to the problems you're showing in your playing. I have a few suggestions for your playing technique. First, you keep making the same mistake when playing legato: your right hand keeps accidentally touching the adjacent strings when you're plucking them. Don't you notice the extraneous noise?"

The bassist's originally arrogant gaze became somewhat dull after Liang Liang's words.

"And your glissando playing, your teacher didn't teach you that the purpose of glissando is to add color to the sound and not to use it too much. Tell me, what's the point of you using glissando so often? This shows that your basic skills are not solid enough, and you need to practice more in the future."

The evaluation of the bassist was rather concise, because there was nothing more to say.

Liang Liang's gaze lingered on the keyboard for a moment before settling on the drummer.

The keyboardist immediately panicked: "Hey! Bro! You can't go over the stove and the kang (heated brick bed), I haven't even said that yet!"

"Sorry! I'm not much better at typing than an idiot. Although I can hear some discrepancies in the key, I can't explain them and can only ignore them."

The keyboardist was a little annoyed; it turned out he was just an extra.

"Although I have some knowledge of drums, I am not a professional drummer and my knowledge of drums is not very thorough. My opinions may be inaccurate. Drummer, please bear with me. If there is anything wrong, just make the corrections as I say."

The drummer was somewhat speechless. "If you're wrong, I'll correct myself according to what you said?"

Just then, Xiao Yu arrived.

"Why don't you play it again and let our beautiful drummer, Ms. Xiao, give us her feedback?"

Xiao Yu knew that Liang Liang was going to make fun of her again, so of course she wouldn't agree.

"Don't look for me! I don't know anything and I won't get involved." Xiao Yu sat down directly on the sofa.

"Since our beloved Instructor Xiao is unwell, I'll have to continue with my comments, even if it offends people. The drum technique for the piece you played was roughly like this: single-hand double-note embellishments, alternating between left and right, double-note bass drum, standard sixteenth notes played with both hands, triple cymbal opening, rhythm cymbal with off-beat light and heavy strikes, and sixteenth notes muted with both hands. The rest were standard interludes, mostly sixteenth notes on the drums, with a single note jump of around 180 degrees. There was a lot of improvisation on the bass drum, and the timing was inaccurate; you probably don't practice your footwork much."

The drummer stomped his feet and looked at Liang Liang. How could he tell that Liang Liang didn't practice much?

"I have a certain level of basic skills and musicality, but I'm still a bit short of being a professional drummer. I'm even behind the drummers in underground bands. I'm a little better than drum enthusiasts, and I need to practice more."

Liang Liang paused here and glanced at the four teenagers.

"In conclusion, you are not yet skilled enough to form a band. You should go home and practice for another six months before coming back."

Yu Xiaolong and his three companions were struck dumb, as if by lightning.

"Liang Liang! Are they really not good enough?" Liu Yuyong felt a pang of pity. He knew the ambitions of these four teenagers, and Liang Liang's comments were a huge blow to them.

"It really won't work! If they can listen to me and make improvements, they can come back in six months!"

It's not that Liang Liang is being disrespectful; if these four teenagers were to actually form a band and go out to perform, they'd probably only be able to fool people in the countryside who don't know anything about music. They'd be exposed as frauds in front of people who know a little bit about music.

It's better to go back and hone your skills than to embarrass yourself now.
