Hey there Lee!

- Back-up will change depending on what the rest of the group is doing…what fits one version of a song doesn’t always fit all the others. The methods Ben teaches are meant to be used as options to “plug in” top places they may fit.
Example: if you play a certain thing behind the guitar and something different behind the mandolin or fiddle or dobro or vocals, you need to pay attention to when and whether each of those might be in the lead …it is a fluid thing that changes, and different styles of backup fit well (or horribly) against different things.
- You can play backup to the rhythm tracks as easily as playing a lead to them. You will find that arrangements change every time you change musicians when out jamming.
Including whole songs with all the parts arranged is an immense amount of work that would take away huge amounts of time spent providing lessons to get you started learning new tunes & concepts.
Including links to other’s recorded material may create copyright issues , as well as give you the idea that there is only one “correct” arrangement to a song. In addition, it isn’t difficult to look up a tune on the internet fr ourselves and this gives us the advantage of hearing different versions of the song and the ability to pick the style and arrangement we prefer to work with.
