Firstly, apologies for demanding answers immediately after joining the forum. As an intermediate player I'm sometimes left confused about which scale to select over certain chord progressions. Taking for example a chord progression made of C major, G Major and A minor (in C) is it acceptable to play the relevant scale over each chord (eg. C major pentatonic over C major; G major pent. over G major; A minor pent. over A minor), or is it advisable to stick to the scale of the key over the entire progression. Obviously this is the case when playing changes in jazz etc., I'm thinking more about rock/ funk styles.
