I have recently been composing and have run into an issue. I have finished a section with a perfect cadence (bar 52), and I would like to change to the subdominant key for the next phrase (bar 53). However, as it stands, bar 53 (Bb7) sounds like a continuation of the previous phrase, and it only feels like a new section when we land on the Eflat M chord in the second bar of the phrase. what is best practice here??
Is it best to modulate to E flat before the cadence at 52? Or best to start the new phrase in B flat and modulate mid-phrase?
thanks Ed
