A common perception is that deriving more than a few elemental abundances ([Fe/H], [$\\alpha$/Fe], perhaps [C/H], [N/H]) requires medium-to-high spectral resolution, $R \\gtrsim 10,000$, mostly to overcome the effects of line blending. In recent work (Rix et al. 2016; Ting et al. 2016) we presented an efficient and practical way to model the full stellar spectrum, even when fitting a large number of stellar labels simultaneously.
