NHCA 2021 Virtual Conference has ended
Welcome to the 2021 NHCA Virtual Conference Schedule, below you will find the schedule listed with 3 types of education sessions, Live Platform, Pre-recorded Platform and E-Poster Sessions. They will all be delivered a little differently so please take a little time to read the descriptions and understand how the conference will be laid out.

  • Live Platforms: NHCA is offering 7 live sessions with interactive Q&A and chat features over the two days of the live conference. If you are not able to watch these sessions live they will be recorded and playback will be available until March 19, 2021
  • ON DEMAND Pre-Recorded Platforms: There will be 28 pre-recorded sessions that will be released on the first day of the conference, these will be available to watch at your leisure and will be available until March 19, 2021. PLEASE NOTE: They are available longer than the 1-5 pm time on the schedule but we are not able to program them in like that!
  • ON DEMAND E-Poster Sessions: There will be 8 E-Poster sessions available to watch, each session is 15 minutes long and worth a quarter of a credit, in order to receive a full hour you will need to watch 4 poster sessions all the way through and complete and evaluation. These will be available as pre-recordings and will be available from the start of the conference until March 19, 2021
This means you have the opportunity for up to 19.0 CE credits at this years conference! (See ASHA AND AAA Brand Blocks below)

ON DEMAND SESSION: Safer choir rehearsals in the period of COVID19

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

Feedback form is now closed.
Reports of deaths from choir rehearsals without masks, where COVID19 aerosols had flooded the room from prolonged loud singing, have resulted in suggestions that the only safe rehearsals are conducted outdoors. An unmasked sneeze can result in aerosols 26 feet from the sneezer, and singing fortississimo can release a prolonged flood of dangerous aerosols in an indoor rehearsal space. As the conductor of a small church choir for 35 years, the author speculated that there might be an alternate approach to reducing risk, including a) wearing effective masks, of course (the N95 mask muffles the singer’s voice, but a mask rated as equally safe does not), b) increasing the spacing between singers to perhaps 10 feet, and c) sacrificing the drama of loud singing, all of which might reduce the risk below “shopping with cloth masks.” Two choir members thought it would be difficult to hear each other at those distances. A quick experimemt with a quartet singing harmony at 12 foot spacing in the Sanctuary resulted in the surprised comments: “It was easier to hear the harmony!” This abstract is too short to explain why, but the reader who took a class in acoustics may recall the reason.

Learning Objectives:
As a result of this Continuing Education Activity, readers will be able to:
1) Identify the music perception at increased distances in choir practices in pandemic.
2) Identify the effects of facial masks on music perception.
3) Loud singing inside choirs without masks has been associated with COVID19-related deaths from the spreading of aerosols.
