Why did Huldrych Zwingli oppose music in the worship service?

Three of the most influential reformers, Martin Luther, John Calvin, and Huldrych Zwingli, took very different approaches to music in corporate worship. Of the three, Zwingli was the most accomplished musician, but he was also the most negative about music in worship – he apparently rejected it completely. Not even Calvin's unaccompanied psalm-singing was sufficient for him. Jeremy S. Begbie writes: > Zwingli was ruthlessly consistent—the intricacies of Latin polyphony, the sounds of the organ, the chanting of the Psalms, the setting of the Mass, even the unaccompanied unison singing of the Psalms in the vernacular (as Calvin allowed) must all go. ([*Resounding Truth*, 115](https://books.google.com/books?id=bLqOBmjGznAC&pg=PA115)) Zwingli's recommendations were apparently put into effect in Zurich: organs were silenced and then destroyed, and in 1525 "the city council enacted the ban on singing in worship." I'd like to explore the reasons for this view. Begbie provides some insight – the [regulative principle of worship](https://en.wikipedia.org/wiki/Regulative_principle_of_worship) played a role, for example, whereas a fear of the worldliness of music did not. But I'd like to see more detail, particularly from the writings of Zwingli himself. For example: - How did Zwingli deal with the apparent commands to sing in [Colossians 3:16](https://www.biblegateway.com/passage/?search=colossians+3%3A16&version=ESV) and [Ephesians 5:19](https://www.biblegateway.com/passage/?search=ephesians+5%3A19&version=ESV) ? - Why isn't the use of instruments in the Old Testament precedent for their use today? - Did he see a difference between a corporately recited prayer and a corporately sung psalm or hymn? - Why not at least unaccompanied exclusive psalmody, like Calvin?
