organize, arranging, tune, tone, meter, key (music)
整 centers on bringing things into proper order: organizing, arranging, and adjusting until everything is in tune. The musical senses of meter, tone, and key are natural extensions of this idea of precise alignment.
整 combines 敕 (a compound of 束 and 攵, suggesting binding or ordering) with 正 (correct, straight). Together they express the idea of putting things in correct order.
The top part 敕 looks like a bundle being tied with a hand, and the bottom 正 means correct. Picture someone binding loose items together and straightening them until everything is perfectly organized.
For セイ, imagine a conductor saying 'say' to cue the orchestra to start playing in perfect tune: 'say' -> セイ, and the music becomes orderly and metered.
