Are there any specific things to look for when determining the tuning of a piece? I don't have any trouble usually if I have a DVD to watch them play or if I have seen them live. But I've been trying to determine the tuning of two Silverchair songs and it's proving very difficult. Someone also told me that none of the transcriptions for Zeppelin's "Ramble On" that I find sound correct because it is not in standard tuning. Any truth to that?
