## Music Theory Intervals • Description
Teachers, students and professional musicians: Recognize simple and compound intervals by sight and/or sound. Compare any incorrect answer to the correct answer.
Includes a 'Grade Book' list of all saved results that you can print or send. 

• Simple Intervals included are major, minor, diminished, augmented 2nds, 3rds, 6ths, 7ths, and diminished, perfect, and augmented 4ths, 5ths, and octaves. 
• Compound Intervals are intervals larger than an octave. 

• Three modes: Audio and Visual, Audio Only (Ear Training), and Visual Only (Clef Notation Training).
• Treble, Alto, Tenor, and Bass clefs. 
• Set how the interval is played; harmonically, melodically up, down, or randomly. 
• Set a random root change, or set the root yourself between each question. 
• Set the number of questions, or stop anytime and grade only the number answered. 

The Grade Book is filterable by name.
Grades include the name, date and time the quiz was taken, all relevant settings (clef, number of questions, etc.), and score (percentage and letter grade).
