These audios sound great, very clear, and I really like the way you sang them, what you said about the rhythm is more clear to me now, thank you, I'll practice them. For some reason, the very first audio link leads me to an error page so I couldn't download it. Indeed, these last few verses are in a much more familiar format, much easier to sing with the traditional tunes I've heard.
Unfortunately, so far I have no idea who Viśveśvarānanda is. I'm assuming Govinda is the former servant of Isvara Puri. Dāmodara Purī is probably Svarup Damodara, right?. The others are mentioned in CC Ādi 9.13-15
"By the communal singing of the names (nāma-saṅkīrtana) of the bhaktas as well as of Śrī Bhagavān and his companions, the forms, qualities, and divine play of Bhagavān gradually appear in the heart of a practitioner. When that happens, aspects of suffering in the form of sins, aspects of offenses which inhibit divine love, and aspects of a subtle dullness taking the form of bonds of ignorance are gradually uprooted, in that order."
I've always liked names of devotees. I don't know why.
Here is my first crack at a recording of the first 21 verses of the GGNKRM. It is flawed, I will be first to admit. Nevertheless, it might give some sense of what the text sounds like when sung or chanted. I will try to refine it and make it more accurate. Eventually, I want the whole text to be available in audio so that it can be used in kirtana. That seems to be the intention of Siddha Babaji in composing the text, that is should be sung and used as a powerful sadhana to develop Gaura and Govinda preman. In the meantime I have noticed that another Vaisnava-vandana has been written, which has been published by Sundarananda, from the 17th century by Devakinandana Dasa. It appears to be in Bengali and not Sanskrit.
Meenoji (Minaketana Ramdasji, my other gurubhai apart from Jagadish dassji), you are a better musician than I. It would be great if, as we progress on this text, you could make a recording of yourself chanting it. I will keep posting updated versions of the text and, of course, I will send it to you in the original. I am very optimistic about it, more optimistic about this than I have been about anything for many years.
Here is the latest version of the Vainava-vandana composed by Siddha Manohar Das Babaji. I have and will continue to work on it. I am almost halfway through it and have sung it as kirtana a few times. You can access it here.
I am also back at work on this. Thanks to Nilamadhavadasji, I do not have to do the transliteration for the text. I can just concentrate on the typesetting and translation. I will have an update in a couple of days.
