I should've seen it coming, The whispers in the night, The shadowed glances cast aside, When trust turned into spite. Your smile was edged with secrets, A dagger dressed in silk, Promises like fragile glass, Shattered at the hilt. The warmth we shared now frozen, As lies took root and spread, Each word a blade, each touch a scar, Where innocence once bled. I should've seen it coming, The storm behind your eyes, But hope is blind and love is cruel, When truth is cloaked in lies.
I agree about the metronome, but why does the chord progression have to be diatonic? Be creative instead. Sometimes stepping outside of a key is much more interesting than playing within it. It all depends on the emotion and imagery you are trying to cultivate.
