Sketch

Comments

This design focuses mainly on allowing a singer to practice the specific songs his or her group is working on.

This first sketch is from the point of view of a singer. The tabs are high level tasks a singer would want, including uploading sheet music, practicing the songs, and reading comments on recordings. The "practice songs" tab is shown. In the left sidebar, there are play options for the singer to hear what the music should sound like. They can check different boxes to hear their own part (boost volume makes their part louder than the rest of the music), practice with the other voice parts or accompaniment, and work on rhythm with the metronome. Below the play options are the songs that can be selected. Selecting a song tab brings up sheet music with interactive notes that highlight as you sing, turning green if your pitch is correct, pink if your pitch is too low, or purple if your pitch is too high. 

Storyboard:
For Anna to practice her solo in The Sign, she first clicks on the "upload sheet music" tab to make the song available on the site. Then she moves to the "practice songs" tab, which shows the sheet music for The Sign. To first work on her solo pitches, she checks "my voice part" under "play options" and hits the play button next to the song title. After Anna becomes more comfortable with her pitches, she checks the Metronome box to practice rhythm with metronome ticks. When she has practiced up to speed, she checks the boxes for "other voice parts" and "accompaniment" to practice having a good ear for her part with accompaniment. Finally, she records herself singing by pressing the record button next to the song title. After her vocal director has had a chance to leave a comment, Anna clicks on her "comments" tab to see her vocal director's feedback on the recording.

Analysis for both sketches:

-Learnability: Generally the learnability will be good since the site has a lot of affordances and external consistency, including buttons, sliders, checkboxes, scrollbars, an arrow for the drop down menu, and tabs. A bad point is that the "play options" section might be slightly confusing in terms of what "boost volume" means and the various options.

-Efficiency: This design is pretty efficient as the tabs are all straightforward, the frequently used sections of play/record/stop buttons and play options are always shown on the screen, and the songs and students are listed as sidebar tabs for easy selection. However, the interface might be made more efficient by adding search bars for songs, students, and recordings if there are a lot of them.

-Safety: Good safety points include the ability to undo most operations, including switching tabs, changing play options, adjusting speed and boost volume, and playing/pausing playback. Some features that might improve safety are rewind and fast forward buttons in case the user pressed play accidentally and a delete option for unwanted recordings or sheet music.

This second sketch is from the point of view of a vocal director. The tabs are similar to a singer's tabs but replace "practice songs" with "vocal exercises" that the director can suggest to singers, consisting of descriptions or links. The "comments" tab is shown with a sidebar of student tabs that reveal each student's recordings and places to leave comments.
Storyboard:
After Anna records herself singing her solo, Bill can listen to it on his own time and leave a comment as her vocal director.
