PitchBop is based on a “Call-and-Response” model.
Each session will contain multiple calls and opportunities to respond. The first call will be preceded by a metronome count-off and then will play a two-measure phrase.
Immediately following the call, the user will respond by trying to play the same pitches and rhythms of the call.
For the remainder of the session, the app and user will alternate between call and response. There will be no count-off after the calls begin.

PitchBop opens in the Game mode. The top heading, “Dr. Bop’s Game” will be highlighted in orange when the app is in Game mode. 
To begin a session, tap the waveform icon just below the top heading and the screen will change. Tapping the waveform will toggle the session on and off.
When tapping the waveform during a session the user will have the opportunity to tap “Continue” to resume the session or “Quit” to return to the Dr. Bop’s Game tab.

The Call and Response screen is what the app will look like when it’s playing phrases for you and listening to your response.

The animated waveform indicates the app is playing when the display is orange and listening when black.

In early levels, the first note being played is displayed. In more complex levels, this will not always appear.

Pitch Complexity
PitchBop creates calls with varying levels of pitch complexity on a scale of 1 to 9.  Use this slider to set the complexity level.

Rhythmic Complexity
Use this slider to set the rhythmic complexity level between 1 and 9.

Metronome
Tap the Metronome icon to set metronome options. Tap again to go back.

In Practice Mode, you can modify many of the parameters to create exercises to develop the specific skills you desire.

The first three options are the same for PitchBop and Practice modes.

Tempo
Use this slider to set the tempo between 50 and 160 beats per minute.

Root
Use the up and down arrows to set the key center.

Scale
Use the up and down arrows to select the scale or harmony area.

Lowest and Highest Pitch
Select the pitch limits of the call.  These might be greater or lesser than the limits set when selecting the instrument.

Always start on root
Toggle between always starting on the root or another pitch.

Calls per session
Use the up and down arrows to set the number of calls between 4 and 32.

Swing/Even
Use the up or down arrows to toggle between Swing and Even beat divisions.

Chromatic notes
Toggle between using chromatic notes or only diatonic notes.

The results screen shows Dr. Bop’s comments on the previous session and tells you what will happen next. Based on Dr. Bop’s evaluation, you will either move up to the next level, repeat the current level, or go back a level.
You will have the choice to proceed immediately or just wait a few seconds and the app will do it on its own.

Under the profile tab you can find information about your progress from each session. This information is only stored for Dr. Bop’s Game, not for Practice Mode.
For more details, tap the up and down arrows next to “Scale” to select the various scale and harmony types PitchBop uses for the calls.
PitchBop will list the total calls and perfect responses for each scale or harmony you have heard.  In addition, it will report the success rate and the Pitch and Rhythmic Complexity of your most recent “Call-and-Response” session.
