GR2: Designs
Project: Pitch Perfect
Problem Statement (recap)
Singers in musical groups often find it difficult to perfect their individual parts in ensemble rehearsals.
They run into obstacles such as:
- not being able to hear themselves among many other voices
- not finding effective ways to practice alone outside of practice
- not receiving individual feedback as vocal directors are usually only able to address groups of people
Scenario
Anna Denkrick constantly gets bombarded by compliments from her friends about how beautiful her voice sounds in karaoke, so feeling pretty good about herself, she joins an a cappella group at her school (about ten members). After the first few rehearsals, Anna discovers that she shines when singing popular, modern songs that she's heard many times before, but unfortunately, her a cappella group just assigned her a solo in an arrangement of the Sign by Ace of Base, a song she's never heard before. As a result, she has trouble hitting the right pitches and going at the correct rhythm. Furthermore, since she doesn't have a good ear for the melody yet, she gets confused in sections where the accompaniment (all of the other parts) is vastly different from her part.
The vocal director Bill Cutter has already spent a couple group rehearsals critiquing her solo, but their performance is only a week away and there are other things the director wants to work on. Anna feels frustrated because she wants someone musically talented to listen to her sing and tell her exactly when she misses a pitch, but no one is able to help her during rehearsal time.
Individual Designs

|
In this design, individual exercises are emphasized, and there are very few ways a user can interact with other members of their group - perfect for someone who just wants to work on the basics on their own. |
|
This design is more social, with something similar to a giant Facebook wall for the group on the home page. There are still exercises, but there is a greater emphasis placed on songs uploaded by the vocal director (the ones that the singer should be practicing). |
|
These sketches are fun and cute but are meant for a mobile application. Since we cannot expect people to spend too much time on their phones, the mobile version is just a collection of short vocal games that the singer can play. |

This design revolves solely around singers and helping them practice their part in specific songs. It includes tabs for basic user operations and has a sidebar with various options to aid practice, including computer playback of different parts to sing along to. The main page shows the sheet music for the current song so the singer can focus on singing the notes. |
|
This design stretch was made for children and is much simpler. Highlighted piano keys are shown instead of sheet music so children can more easily understand the music they are singing. The basic play options are located at the top of a tabbed page through big buttons and sliders with simple descriptions. The bottom shows feedback in words while the piano keys also light up in different colors to indicate a correct (green) or missed (red) pitch. |
|
This design is specific to different user classes and therefore more personalized. Singers and vocal directors can create accounts and click on the tab that is specialized for them. Singers see the sheet music for the song they are singing, general comments made by others on that song, and different play, record, and upload functions. Visual feedback for pitch matching is also given on the notes, where notes are highlighted as the song progresses and a green note indicates correct pitch, purple indicates too high of a pitch, and pink indicates too low of a pitch. Song selection occurs in the bottom of the sidebar where the current song is highlighted. The "for vocal coaches" tab would show options for uploading sheet music and leaving comments on recordings by different singers that the vocal director is coaching. |

The first sketch is more meant for personal use, with little group interaction. There are tabs on the side for easy access to the different sections of the site. The user can practice a variety of singing exercises, and can also play and record songs that the vocal director has uploaded onto the site. The director can listen to the recordings and make comments. |
|
This second design is focused more on social interactions among the group. The home page displays an activity feed with comments from the vocal director. There are no exercises on this site, but there is more focus on the singing section. Group members can highlight music sections on the sheet music and make comments to the user. |
|
The second design has a member directory that lists times that users are free to meet outside of practice. The singer can then contact the group members by sending messages in the site. |
|
For the third design, I tried to make an extremely simplistic design that would fit well on phone screens or just small screens in general. The home page is a group of 4 icons. The exercises are in a swipe-able format (Tone Exercises: A, B, C etc.) which is convenient for phone screens. The recording section no longer shows the sheet music because of the small screen size but instead shows the singing waveform. |
Storyboard Designs
* Storyboard 1 - Exercise-Oriented Design

Comments |
---|---|
|
This design emphasizes an exercise-oriented approach for singers to get better. Notice that each page contains sketches of two different pages. |
|
Once she clicks the link, she is brought to the page with that specific tone exercise, shown to the left. She can see her last score, as well as a record of what happened during the last game she played. |
Analysis:
-Learnability: Generally, the learnability will be good, since the site has a lot of affordances and external consistency. These aspects include play buttons (for both song playback and recording playback), the record button, drop-down menus, and input fields for the various exercises. However, for a new user, it may be difficult to internalize the difference between "Exercises" and "Practice", so we may wish to watch our wording there.
-Efficiency: For an experienced user, this interface is not that efficient. There is no way to search for a particular exercise, and if the user has a lot of songs, the drop-down menu for "Practice" will get very large and unwieldy.
-Safety: Although not shown in the sketches, the user can delete recordings, which is a good safety point in case he or she accidentally pressed Record. The exercises themselves could potentially have poor safety if all of the exercises shared the same general page layout - the user that does not read the instructions may mistake one exercise for another.
* Storyboard 2 - Social-Oriented Design
Sketch |
Comments |

|
This design emphasizes a social-oriented approach for singers to get better. Notice that each page contains sketches of two different images. |
|
Once Anna gets to the song page, she notices that her director has highlighted a particularly tricky few bars and left a comment. She begins practicing, playing the song back a couple of times, and then creating a recording, which she marks public so she can get feedback. |
|
Here, at the members directory, Anna can see that Amy is free on Monday and Wednesdays at 3pm, and she can send Amy a private message suggesting a meet-up time. In case she forgot, she can also see that Amy sings the Harmony 1 part for the song they want to practice. |
Analysis:
-Learnability: The learnability of this site for recording and playing music is good because there are affordances and external consistencies with the play and record buttons and drop-down menus. The highlighting notes feature in the sheet music would be difficult to discover for a new user though because it is not explicitly explained on the website and the user would not know it existed unless someone else showed them.
-Efficiency: Overall, efficiency is pretty good because the drop-down menu is simple. It is straight-forward to go to current recordings because they are linked in the side-bar. Some things can be improved though. For example, after looking at the notes on the sheet music, Anna has to go the directory to mail someone. The site could allow users to go straight to another user's profile by clicking on their comment on the sheet music.
-Safety: We need to be careful about the comments on the sheet music. There has to be some mechanism that prevents users from accidentally deleting another person's comments if they highlight the same group of notes. Also, there should be some mechanism that allows users to delete recordings they do not want.
* Storyboard 3 - Practice-Oriented Design
Sketch |
Comments |
---|---|
|
This design focuses mainly on allowing a singer to practice the specific songs his or her group is working on, as well as allowing vocal directors to give feedback for those songs. These two user class are differentiated by user accounts. |
|
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:
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 listen to the recording on his own time and leave a comment, Anna clicks on her "comments" tab to see her vocal director's feedback on the recording.
Analysis:
-Learnability: Generally the learnability will be good since the site has a lot of affordances and external consistency. These aspects include buttons, sliders, checkboxes, scrollbars, text boxes, an arrow for the drop down menu, sidebars, and tabs. A bad point is that the "play options" section might be slightly confusing in terms of all of the various options and what they might mean when a user sees them for the first time.
-Efficiency: This design is pretty efficient as the tabs are always consistent and straightforward, the songs and students are listed as sidebar tabs for easy selection, and the frequently used sections of play/record/stop buttons and play options are always shown on the screen. 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 or wanted to skip to a certain section, as well as a delete option for unwanted recordings or sheet music.

Scenario: The scenario given set a very good motivation for the use of the system. However, it would have been good to outline the concrete steps in the scenario that Anna and Bill would be going through in using the system.
Preliminary designs: Individual Designs: Great variation in designs. Even given your very novel domain, I think that you have taken steps in ensuring that your designs were varied and focused on different aspects for the user. The designs for mobile were also interesting! I really liked the idea for thinking about designing for children as an ultra-learnable system, though keep in mind that your user population has already been defined! Across the group members, even designs with the same overall tasks had very different implementations, which was really good to see. To focus on ultra-simplistic was also interesting, and helps you focus on the most important tasks at hand for the user.
Storyboards: Really, really good job with some of the synthesized designs! The storyboards were clearly described, and I think the group did a great job in choosing the strong points from the individual designs and coming up with really good combined designs. I think the analysis that was performed was very, very well done, particularly with very precise explanations and use of concepts and terminology from class.![(sad)](/confluence/s/tichzu/8804/z1btw/_/images/icons/emoticons/sad.svg)
Wiki Presentation: I really appreciate laying everything out into tabular format, it made it very easy to go through. However, one thing that I would have liked would be to enable zooming or an enlarged preview for the images! They look so interesting, but I couldn't see some of the little details written in them because they were a little small
