We propose to use EMIR to obtain near IR spectroscopy of many thousands Galaxy sources, mainly located in the inner regions. These will be selected from their position on IR colour-magnitude (CM) diagrams and will include disc, bar bulge and ring sources. The principal aim is to accurately classify the sources to provide a better understanding of, particularly, the redder parts of a infrared CM diagram. Without this information there will remain ambiguities in the interpretation of structures in the inner Galaxy.
