SOPP423: How much such displays help in singing

This question was sent by Damian, and he writes: Hi Vidas, I've been catching up on podcasts lately and I'm very pleased that you've touched the topic of my little device. It is a very simple solution from the technical side and there is nothing revolutionary in it, maybe only the application is unusual ;) In Poland, displaying song text in churches is very popular, at least in my area there is a display in every church. The ways are different, from the old school slide projector, through the large TV, to the LED displays, assembled by specialized companies in this field. I also know that in some regions of the country the organist only displays the number of the song, and people have the books in which they find the text. A separate topic is how much such displays help in singing. Decades ago, we didn't have such inventions, and people sang much better. It was because they wanted to sing and sang a lot, and what follows, they knew the lyrics by heart. I do not know how it is in Lithuania, but in Poland, the desire to sing in the church is getting worse, especially among young people. Indeed, displaying the text helps if you sing a less-used song, or further verses, but only to people who want to sing. Sometimes I get the impression that these displays try to "improve" the singing, make people sing more and "as before". Nevertheless, in my opinion, they will not encourage people who do not want to sing anyway, and the problem lies in the fact that contemporary people sing less and less. Thus, technology helps, but to a limited extent, and unfortunately it is not easy to eliminate the unfavorable changes taking place in singing in parishes. Damian
