Raag Styles question

waheguru ji ka khalsa waheguru ji ki fateh

Question for the Raagi Gyanis and Ustaads: I am trying to differentiate between the main raag keertan styles.

In the big Gurdwaras, the tanti saaj Raagis sing in a sing-a-long fashion (repeating melody, rapid progress through the shabad). However there is another rarely heard style where the singing is very different: substantive vibrato/voice echo, slow progress- once verse may be chewed upon for a very long time with great emotion and improvisation. Listen to the following two clips which demonstrate this (Man Japoh Ram Gopal - 1 in 'sing-a-long' style and 2 in the 'slow tempo' style).

-Are there any names to describe these two types of vocalisation? Is it correct to say that the vocalisation of the latter is a genre such as Dhrupad?

-In simple terms what is the difference between the two? Do they have the same core basis?

-Can all ustaads teach the second type?

Sample 1-Raag Kanra- Man Japo Ram Gopal-Prof Surinder Singh.mp3

Sample 2-Raag Kanra- Man Japo Ram Gopal-Ustad Harbhajan Singh, Balwant Singh Namdhari..mp3

I've been told that the latter slow tempo style is classical/dhrupad/semi-dhrupad but the question remains whether they have the same core basis and whether all ustaads can teach the second type?

Any assistance will be greatly appreciated.
