I have had a lot of fun and (re)learned a lot playing with PGS. I have* finished the Rookie level and am working through Intermediate with some songs on the side. As far as timing, note reading, hand gymnastics, some theory, and just having fun playing go, those are covered nicely. I sincerely want to thank you for that!
There are, however, aspects that I'm really missing and that I know would be a very important part of any "human" lesson. Some things would be hard to impossible to address (e.g. back, arm, hand posture) but others should be doable IMHO.
The most important ones:
- Note duration played. Other than for tied notes the program does not check how long we hold notes, in both directions (too long or too short). This is essential and something a piano teacher would correct immediately. There is a mention of this over one year ago by Sean that this is a planned addition so I hope it will be added soon.
- (Relative) loudness (Forte, Piano, etc and difference between voices) evaluation. Maybe this is part of the more advanced lessons but I have not seen it while looking for it. Again, really important, something that is measurable and could / should be evaluated by the software. No human teacher would ignore this aspect, starting from early on.
- Pedal use. Maybe not quite as important as the first two points, and again maybe you address it in the more advanced lessons, but I really would have expected his to be part of the intermediate courses. Again something that could quite readily be evaluated by software.
* had! happy to see you keep adding lessons!
