Identifying Appropriate Chords in Teaching and Learning Posted February 28, 2014 Short answer: no. Long answer: you need to get to know the chords which will normally be required for the key you are in. For example, in G major you will likely need G, D, A minor and/or C, E minor. Try these in an effort to help the tune on the tonal journey it's trying to go on. If a chord sounds wrong, try another one. If it sounds good, stick with it (but bear in mind there may be a better one). If you're playing folk stuff, you mostly won't need too many chords. If it's 'tin pan alley' songs, you will need many more. Good luck.
