Displaying an input at multiple octaves

A computer program product, tangibly embodied in a computer-readable storage medium, the computer program product including instructions operable to cause a data processing apparatus to:

• receive, via a microphone in signal communication with the data processing apparatus, a music performance input data;
• display, on a display in signal communication with the data processing apparatus, a first pitch marker reflective of the music performance input data;
• and
• display, on the display, substantially simultaneously with the display of the first pitch marker, a second pitch marker at a vertical offset from the first pitch marker, the offset indicative of an octave difference between the first pitch marker and the second pitch marker.

A system comprising:

• a data processing apparatus configured to:
• receive, via a microphone in signal communication with the data processing apparatus, a music performance input data;
• display, on a display in signal communication with the data processing apparatus, a first pitch marker reflective of the music performance input data;
• and
• display, on the display, substantially simultaneously with the display of the first pitch marker, a second pitch marker at a vertical offset from the first pitch marker, the offset indicative of an octave difference between the first pitch marker and the second pitch marker.

An apparatus comprising:

• means for receiving, via a microphone in signal communication with the apparatus, a music performance input data;
• means for displaying, on a display in signal communication with the apparatus, a first pitch marker reflective of the music performance input data;
• and
• means for displaying, on the display, substantially simultaneously with the display of the first pitch marker, a second pitch marker at a vertical offset from the first pitch marker, the offset indicative of an octave difference between the first pitch marker and the second pitch marker.
