I've recently joined an EDM band. Things are going quite well so far but the band leader has loosely put forward the idea of band members swapping instruments for certain songs in a live situiation (the band being guitar, bass, keys/synths, drums and vocals). I don't mind playing a few chords on a keyboard when the bass isn't needed but swapping instruments is something I've never been keen on. In my mind, me swapping instruments with the guitarist would be pointless. My knowledge of the guitar is limited and likewise, the guitar player isn't much on the bass so to swap would only mean that both of us would be wasting our potential with our respective first instruments. Besides this, I know alot of musicians (many more experienced than I) who would share my view that this is something to be avoided. In the classical music world, a violinist is not going to trade places with a pianist or cellist just for the sake of "looking cool." It's also rare elsewhere and I've only ever really seen it when the bassist is just a guitarist playing bass (something very common among alot of bands here). To give a real world analogy for my opinion here, consider the following. I work as a software engineer, specialising in Databases. In my dev team, there are two programmers who do not work with the databases, only with application coding. Now, I understand how to program and the two guys are knowledgeable of databases so in theory, we could change places and possibly function. However, if we did, we would be outside of out experience remit and thus, unable to produce work of the same quality as we had previously. To cut to the chase, I've essentially said that I'm not comfortable with swapping instruments for the reasons outlined above. I don't know how the guitarist feels but I don't thin he's too pushed either way. The band leader, thankfully, hasn't pushed the idea but if it comes up again, would I be right to stick to my guns?
