It would be helpful if there was a small arrow next to the notes that show if the string should be picked with an upward or downward stroke.

That way, the player can see whether he should use economy picking, alternate picking or some other combination in more complex songs.

It would be a great tool since inexperienced players wouldn't have to guess how to play a certain part.

achievements for certain milestones

It would be great if I could look back at a song that I’ve just played, so I could see which notes I’ve missed that caused a dead note in a chord, and to also see how my timing was (late, good, perfect, etc).
When I practice I try to count in my head and also not look at the song I’m playing; I may think I nailed it only to see that I’d missed some notes/chords.

I am using MIDI over USB so i can hear my pianos original sound and yousician as well. In the song mode, users have the option to silence the midi synth but then in the rest of the app I hear both my keyboard and yousician's MIDI synth which is quite annoying. It seems like it would make sense to allow users to disable yousician's synth altogether or just respect the midi setting across all surfaces of the app.

It would be convenient to have a drop down list of the accounts in your family plan that don’t require passwords to toggle between.

Hello. I’m in the section building speed and wish there was a way to see someone playing to see how to place fingers for speed and accuracy. Kinda like tips and tricks. E.g. when moving higher on the fretboard, which fingers are best OR when you have notes in the same fret but different strings (one after the other - like in Samba Ukulele).
Thank you for considering

A more standard color scheme for the piano

There is very limited content for 5 strings bass and no content for 6 strings bass. I think it's going to be quite cool to add songs and/or exercises for 6 string bass as it's harder to find quality content online.

Ability to practice with varying pitch and length instead of the same pattern.

I think it would be nice to see which chord each measure is in for leads and melodies. I think this would help us learn about scales as we could see what chord would be played along with the notes you are playing. This would benefit us as seeing the location on the fretboard the notes we are playing over the chord for each measure of the song.

I'm proposing to have a kids' or children's song selection or genre readily available (I'm focused on guitar learning but can imagine this applies to other instruments as well).
It would be great to have the song text available with the notes for singing along as a secondary feature.

Search filter for chords, rhythm, melody to improve search results when looking for songs.

I am not a fan of the color scheme yousician has in place. I would really like to be able to choose my own color scheme. For example:

Finger 0 - White
Finger 1 - Blue
Finger 2 - Green
Finger 3 - Yellow
Finger 4 - Orange

I would also like to change the background color from the pea green to something more appealing to me.

I understand that it is your brand, and I am not suggesting to change that, but give players/customers a choice of color schemes that are easier for them to follow.

I think that I would be able to follow along with the songs much better if each string was a specific color, instead of the frets changing colors. It would be awesome if we could have a little more option for how its set up. Thank you!

Just a space on the app where you can chat with other yousicians online about lessons, challenges, etc.

ability fo the app to provide a detailed feedback and statistics after a performance.
