> All these 3 variants, 12-beat, 24-beat, and 48-beat ones of Ektaal have developed 3 different khada theka
While there is indeed a kernel of validity to what you say, I feel you
are reading too much into this. Khanapuri excluded, the difference in
theka is minimal. Moreover, it can be conjectured that some
differences have been incorporated as useful markers to indicate to
the vocalist which part of the avartan is being played. I'd say the
Na---na-na- of the sixth matra of Vilambit Ektal is a good example of
this.
> The 12 beat one itself have two different theka, one for Madhyalay/Vilambit, and another for Drut/Druta-Madhya.
Surely an overstatement once again. Apart from compressing Tirakita
into Traka, the other differences are both minor and inconstant, or at
least non-standardised.
> Listen to Sharafat Hussein Khan's Puriya
There are more than one, surely. I have a three-hour long recording,
and another one of 90 minutes (in tape format). Which one do you refer
to, and at which point in time?
> Amir Khan Sa'ab and also Abdul Waheed Khan Sa'ab sometimes skipped one Sam in 56-matra cycle and thus made it 112-beat cycle
I disagree. Merely skipping a sam (by which you presumably mean not
singing the mukhda at the sam) does not mean that the avartan itself
has doubled in size. Not singing the mukhda is quite usual when
singing at not-so-ati vilambit laya. I remember coming across an
atrocious Hamsadhvani by Raza Ali Khan. It was set to moderately
vilambit ada-chautal, and he made it a point to sing the mukhda at the
arrival of every single sam. Can't tell you what a torture it was.
> I am talking about Vilambit only, which according to this table was 40 beats/min and my preference was and still is 45 beats/min.
A long time ago I had tried my hand at writing a tabla software. After
timing a few pre-recorded avartans, I arrived at something between 10
and 12 beats a minute for at-vilambit laya (say, Amir Khan-style
Jhoomra), that is, if ti-ra-ki-ta counts for one beat. Going by this
calculation, 40 beats a minute makes for two beats every three
seconds, certainly a pretty brisk avartan. Amir Khan's HMV
Hamsadhvani might be around that mark.Personally I'd say that's well
within Madhyalaya parameters, regardless of what the label says. On
the other hand, if you take ti-ra-ki-ta as four beats, then this 40
BPM will translate to 10 BPM by my system of calculation, which lies
at the slower edge of ati-vilambit laya.
> The Laya in Ektaal is not always picked up from Ti-ra-ki-ta spacing, the 48-beat Ektaal might even skip that bol, while in Vilambit Jhumra it can't just be skipped. Listen to Nissar Hussein Khan's Puriya Dhanesree (76 min)
One freak instance does not a rule make. I'd attribute it to
obstreperous sangat more than anything else.
