Dual instrument (C&R) based perfect symmetry with bridge

This involves a number of call and response arrangements that have a symmetrical pattern and also includes a musical bridge.  With two instrument based C&R arrangements, I have not observed any symmetry around a bridge.  In other words, I have not come across a Raja composition that has a musical bridge in the center with perfectly symmetrical C&R arrangements on either sides of it.  In the previous post, there were two songs that had perfectly symmetrical but had a bridge at the end of the interlude. For the purposes of demonstration of a perfect symmetry with two instruments, we ignored the bridge at the end of the interlude.

Dual instrument (C&R) based imperfect symmetry with bridge

This involves a number of call and response arrangements that have a pattern and also includes a musical bridge. With some exceptions, the arrangement is symmetrical. This again is not an easy one as there are fewer compositions that use two instruments in a C&R arrangement throughout an interlude 

Vasantha Nilavin from Sooryan (2007 Malayalam) is a song that qualifies. The second interlude of this song is primarily a two instrument arrangement – Veena and a synthesizer. The arrangement patterns is as below:

Sy-Ve x2

Sy br

Sy-Ve x2

Sy Br

Sy-Sy x2

From a symmetry point of view, this is imperfect as the Sy x Sy arrangement breaks the symmetry. There are several combinations of ideal symmetrical arrangement with a bridge for this combination. However, this is more of a theory and no guarantee of a great melody as the current Raja arrangement is quite melodious. As this interlude is short, it could be still symmetrical with some extension.

Sy-Ve x2

Let’s hear the imperfect, but melodious two instrument arrangement of Vasantha Nilavin…
