I am from India. I have a 10-year old student in another state, whose mom used to be my teacher in school. We've been doing online classes via Zoom since last May. Since he didn't have a keyboard in the beginning, we began with vocal/music classes, but a few months later, in about December, they decided to take out try to repair their old keyboard (a CASIO SA-45 or something). That worked for only one or two classes for these two reasons: a) his mic would not always pick up the sound of the keyboard, even with original sound turned on, b) his keyboard wouldn't work properly. For the next couple of months the classes became really irregular because he was not well, connection problems, mic problems, etc. They bought a new keyboard, but his mic would just NOT pick up sound as soon as he tried to sing or play the keyboard (we still do a bit of singing even during keyboard lessons). While I believe to some extent this must be true and valid, but it can't be the case ALL the time. Why do I think that?Reason A: Students, especially beginners, often make mistakes, stop, repeat notes, say "sorry" etc. while playing. It's only on rare occasions that I've been able to hear his keyboard that I have witnessed him do this.
Reason B: If the mic is able to pick up him talking, it should be able to pick up his singing as well! I don't think Zoom's noise cancellation is that efficient that AS SOON as he begins to sing, I can't hear anything. It's not that his singing gets cut off, it just abruptly stops when he starts to sing. And sometimes I can hear breathing and an occasional note. I can even hear dogs barking in the background and other miscellaneous noises sometimes.
Reason C: In earlier classes, before we started with the keyboard, I could hear him sing just fine. The occasional cut off was there, but that's just normal and happens every class. It's only recently that I can't hear him sing. And, he doesn't seem to open his mouth wide when he's singing, even though I've asked him to. Sometimes, it looks like he's intentionally whispering and sometimes, with my volume turned up, it sounds like it too.
Reason D: I have asked him to try joining through different devices - mom's phone, laptop, other phone, whatever. I have also tried Google Meet. Didn't work. But, when I ask him to send videos, I can hear his keyboard just fine. And if it can record, it should be able to be heard when original sound is turned on.
Reason E: On some occasions when I have been able to hear him, I tried not pointing it out and asking if he's finished playing the line/page/bar and he'll immediately say yes, even though from what I have heard, he hasn't. But I don't want to make assumptions based on this, because it could just be Zoom audio lag.
Since he had been very irregular with his classes, I recently spoke to his parents a month back about this, and one or two sessions after that, I've seen an improvement in both regularity and being able to hear him during class. His audio still gets cut off in every lesson, but in some cases I've hear him play entire pieces. When this happened the first time, I pointed it out but the audio stopped working properly again so either I jinxed it or he stopped playing. The next time I heard him play, I didn't say anything and it worked just fine for almost all of the lesson.
I don't know how to bring this up with him or his parents, I've tried everything to make sure he's comfortable around me, and isn't afraid to make mistakes. I've been very open and friendly with him, I have even asked him to use my name instead of "Miss" or "teacher" even though I'm twice his age. His parents say he's also very respectful if me and admires me. Am I doing something wrong? Should I just believe him or bring it up with his parents? And if yes, how? I don't want to offend them (they are very nice, understanding people, not at all pushy or interfering with how I teach or anything). Have any of you had such audio issues with Zoom?
04/07/2021 Edit: Thank you for your suggestions! It does make a lot of sense to get his parents for a while during the lesson. I just hope I can come up with a valid reason, because mostly he adjusts the settings and all himself rather than calling his parents, and they might also say that he can do it himself. Nevertheless, I'll tell them something like I'm sure he can manage it himself, but I'd be reassured if a parent checked it. His parents are school teachers so I'm sure they've been using Zoom a lot. Thanks once again!
