Short answer IMV&E, depends upon a song's complextity, & relative difficulty to the individual learning it.
Learning BIB with Mike in this series of lessons, until I am sufficiently advanced in my skillset I can just watch them sequentially then play all the parts as demonstrated and taught instinctively off the cuff, i.e. verse, chorus, solo, and other supporting parts, I'd approach it as the lessons are planned. Although I have learned and can play songs of similar complexity of this to a competent performance standard, I can't do that yet, so here's how I do it.
I break the song down into parts or sections at the pace personally required. For me initially, other than the chord parts, that's copycat slow. Once I've learned the base fingering and my motor skill coordination is of a standard I can play the part consistently competently, I speed it up to tempo, if necessary in BPM increments. BIB at 92BPM isn't at a challenging tempo, so for me would probably be learn the riff & or lick, then go straight to practising it at tempo. Then I'd practice that and develop any nuance a song might require. e.g. the low E bend to tone & the vibrato on the C in Led Zeppelin's "Heartbreaker" riff which might not be apparent when initially getting it together until I can perform it all consistently at tempo without fumbling or making a mistake 90% of the time.
[br]Once I have a section/lesson segment/ part up to that standard, I move on to the next, and subsequently the next. Doesn't have to be "mastered" as in virtuoso perfect, but just [u]consistent[/u] and sufficiently [u]comfortable[/u] with the part with mistakes or fumbles becoming less frequent. As I learn each part, I revise the former and the exposure and confidence developing over time in conjunction with this process takes care of that. Along the way I'll stitch the segments together playing as far as I've learned. Once have all the parts accomplished using this method, I put the song together and practise the entire song using the same methodology. [u]Pretty much the lesson verbatim as taught here really[/u].
It's definitely the solos where I spend the most and disproportionate amount of time, and in "Back In Black" too that's where the majority of my time would be spent.
By way of comparison, easy version songs like Caren's rhythm version of "Proud Mary" without an actual solo I might learn in an hour and be able to play it through fluently in that time. Others like "Paranoid" where I was circa two and a bit years in when I tackled it? It didn't take long putting together the intro riff, verse & chorus. Tackling Tony Iommi's solo back then was inarguably a challenge for me. I broke it down into sections, learning each until fluid with it first. This developed confidence along with my motor skills as well as learning the part. Nevertheless back then it took me a week maybe ten days learning the solo putting in the time (I'm retired) and persistent effort every day, and longer practicing and polishing my motor skills to get it consistent & rote in muscle memory so I could transition to the initial bend quickly enough and bend to tone accurately to play the solo at tempo before putting the lot together as a song beginning to end.[br][br]Polishing phase for me is then is to play a song entire consistently at tempo. Final phase is do the same, but to a bass and drums backing track, with vocals if available. Continuation is regular revision in my song repertoire/set list.
[br]Four years in this Christmas. How I do it. Hope something in the above resonates with you. Cheers. [br][br]
