قد ما الجمهور يصفق، المغني بيغني اكتر.

In this sentence, قد ما introduces a degree relationship: the more X, the more Y.

So:

• قد ما الجمهور يصفق = the more the audience claps
• المغني بيغني اكتر = the more the singer sings / the singer sings more

Depending on context, قد ما can also mean as much as or however much, but here it is part of a correlative pattern: one thing increases as the other increases.

Because الجمهور is a collective noun. Grammatically, it is usually treated as singular masculine.

So:

• الجمهور يصفق = literally the audience claps

Even though the audience contains many individuals, Arabic often treats words like الجمهور as one unit.

If you wanted to emphasize the people as individuals, you might use a plural expression instead, such as الناس or الحضور, and then a plural verb could appear.

This is a very good question, because learners notice بـ quickly in Levantine.

In Levantine, بـ often marks the normal present / habitual form:

• بيغني = he sings / he is singing in the usual colloquial present

But in dependent clauses after expressions like قد ما, speakers may use the bare imperfect:

• قد ما الجمهور يصفق

So here, the first clause is a dependent degree clause, and the second is the main clause.

Also, in real speech, many speakers would also say:

• قد ما الجمهور بيصفق، المغني بيغني اكتر

So the version with يصفق is understandable and natural, but it sounds a bit more neutral or slightly less strongly colloquial than بيصفق.

اكتر means more. In Levantine it is the common colloquial form of Standard Arabic أكثر.

Here it works like an adverb, modifying the verb:

• بيغني اكتر = he sings more

So it does not mean more singer or a bigger singer. It means the action happens to a greater degree.

This is what creates the pattern:

• قد ما ... ، ... اكتر
• the more ..., the more ...

Because in everyday Levantine, subject + verb order is very common.

So:

• الجمهور يصفق
• المغني بيغني

sounds very normal in speech.

Arabic can also use verb + subject order, especially in more formal styles or for a different rhythm/emphasis, but colloquial Levantine often prefers subject-first structures in ordinary statements.

So this sentence sounds natural for spoken-style Levantine.

In many urban Levantine dialects, it is often pronounced something like:

• ʾadd ma

That is because ق is often pronounced as a glottal stop in urban speech.

Depending on the dialect, you may also hear:

• qadd ma
• gadd ma

So the spelling stays قد ما (sometimes قدّ ما), but the pronunciation changes by region.

Yes, but it would change the feel a bit.

• بيغني = simple present / habitual / general statement
• عم بيغني = emphasizes an ongoing action right now

In your sentence, بيغني is a good choice because the sentence expresses a general pattern:

• the more the audience claps, the more the singer sings

If you say:

• قد ما الجمهور يصفق، المغني عم بيغني اكتر

it sounds more like you are describing a specific live moment happening in front of you.

Sometimes yes, but the nuance is different.

• قد ما focuses on degree / amount
• كل ما often means whenever / every time and can also be used in repeated-change patterns

So in this sentence, قد ما is especially good because the idea is:

• the amount of clapping increases
• and the singing increases with it

A learner-friendly way to think of it is:

• قد ما = the more / as much as
• كل ما = often whenever / every time, and sometimes the more depending on the pattern

So قد ما is a very appropriate choice here.

Because this is colloquial writing, not strict Standard Arabic spelling.

In spoken Levantine, people often write words the way they say them, and they often simplify spelling in informal contexts. So:

• اكتر = colloquial spelling
• أكثر = Standard Arabic spelling

Both point to the idea more, but اكتر looks and feels more Levantine and conversational.

It sounds understandable and usable, but it is a bit mixed in register.

Clearly colloquial parts:

• بيغني
• اكتر

Slightly more neutral or closer to Standard:

• الجمهور
• يصفق

A very everyday Levantine version might be:

• قد ما الجمهور بيزقّف، المغنّي بيغنّي أكتر

Here بيزقّف is a very common colloquial verb for clap/applaud.

So your original sentence is fine, but some speakers might choose a more colloquial verb for clap in casual speech.
