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.
