This advanced module provides comprehensive training on musical related tasks. There are seven
training groups in this module which target at different levels. 。
Group 1: Music Note Discrimination Training
In this group you gain practice in discriminating between different music notes. The training may help your ability
to hear differences in the pitch of sounds, a good starting point in developing your language recognition and music
perception skills. By listening carefully to the music notes during training and testing, you are given a better sense
of the different pitches provided by your cochlear implant.
How the Training Works
All levels present discrimination tasks. In each task, three sounds (music notes) are played, and their
corresponding response buttons highlighted. Two of the sounds are the same music notes, while the other sound
has a different pitch. Click on the response button you think has the different pitch. As you move up through the
levels of difficulty, the tone comparisons (the semitone differences between music notes) become more closely
spaced and therefore more difficult to discriminate between. Please perform one testing before the training to
determine which level you should be trained. At level 1, the tone comparisons are widely spaced. By level 5, the
tone comparisons are the most narrowly spaced. Some tone comparisons may be very difficult, so don't be
disappointed if you cannot discriminate all the tones. Figure below shows the response choices.

Group 2: Melodic Contour Identification Training
While a cochlear implant provides many patients with excellent speech understanding in quiet, music perception
and appreciation remains a challenge for most cochlear implant users. Recent studies have shown that a closed-
set melodic contour identification (MCI) task could be used to quantify cochlear implant users’ ability to recognize
musical melodies [Galvin, J.J. III, Fu, Q-J., and Nogaki, G. (2007). “Melodic Contour Identification in Cochlear
Implants,” Ear and Hearing 28(3), 302-319]. This training group provides MIDI-based Melodic Contour
Identification Training for CI patients to aid them in improving their recognization of melodies, thereby improving
their music appreciation. For the MCI task, test stimuli were melodic contours composed of 5 notes of equal
duration whose frequencies corresponded to musical intervals. The interval between successive notes in each
contour was varied between 1 and 5 semitones; the “root note” of the contours was also varied. Nine distinct
musical patterns were generated for each interval and root note condition. This is a screen shot of the display
window.
How the Training Works
Melodic contour identification performance was tested by using nine five-note melodic patterns. The nine patterns
represented simple pitch contours (e.g., “Rising,” “Flat,” “Falling”) and changes in pitch contour (e.g., “Flat-Rising,”
“Falling-Rising,” “Rising-Flat,” “Falling-Flat,” “Rising-Falling,” “Flat-Falling”). Figure below shows the melodic
patterns and response screen used in the MCI test and training.

Level 1 (note separation):
5-6 semitones
•
Level 2 (note separation):
3-4 semitones
•
Level 3 (note separation):
2 semitones
•

Group 3: Melodic Sequence Identification
This group uses both Open Set Recognition Training Protocols and Speech Synthesis based on Concatenation for
assessing/training the listener's ability to identify melodic sequence. The training group is an advanced version of
melodic contour identification. The original melodic contour identification only have nine different patterns while
the melodic sequence identification allows much more melodic patterns, which is much more difficult than the
original melodic contour identification. The interface for this training group is displayed below.

•
Level 3 (note separation):
+1, -1 or 0 semitones difference between the succesive notes
•
Level 4 (note separation):
random semitone difference between the succesive notes
Group 4: Music Chord Identifcation
In this group you gain practice in discriminating between different music chords (combinations of three concurrent
notes). The training may help your ability to hear differences in the timbre of chords, a good starting point in
further developing your music perception skills. By listening carefully to the music chords during training and
testing, you are given a better sense of the combined notes provided by your cochlear implant. Depending on the
level of difficulty, the interface for this group is different. In the preview mode, you are allowed to preview all the
chords used in the program.
Training Level Summary
Number of trials:
25 per run
Number of stimuli:
24
Training method:
Discrimination, Identification and Acoustic/Visual Feedback
Response choices:
3 (Level 1), 2 (Level 2), and 6 (Level 3)
•
Level 1 (Discrimination):
To detect the difference between any Chords
•
Level 2 (Identification):
To identify whether the Chord is Major or Minor.
•
Level 3 (Identification):
To identify which chord is playing from the six choices
Group 5: Music Contour Segregation
This training group help cochlear implant users segregate competing voices and/or musical instruments.
Polyphonic music often involves multiple instruments that interleave and overlap in time, and listeners may use
temporal offsets between instruments to track different melodic components. When played simultaneously by
multiple sound sources, it is more difficult to track the melodic components. In the present study, the masker and
target were presented simultaneously; the onset, duration, and offset for each note of the target and masker were
the same. The response interface is same as melodic contour identification.

Group 6: Music Instrument Identificagtion
This training group help cochlear implant users improve the identification of different music instruments.The first
training level is to identify the instrument from six different instruments. A five-note sequence will be played. The
subjects determine the instrument based on the sequence played. The response interface is shown as follows.
Training level 2 to 4 is to recognize the sequence of instruments with single note. It is much difficult than the level
1. The response interface for these level is shown as follows:

Group 7: Familiar Melody Identification
This training group help cochlear implant users improve the identification of familiar melodies either with rhythmic
cues or without rhythmic cues. Familiar melody identification was also measured for 12 familiar melodies used by
Kong et al. (2004, 2005), with and without rhythm cues. Three-harmonic complexes were generated for each note,
using the same methods as for melodic contours. The F0 range covered by all melodies was 415 to 1047 Hz. The
response interface is shown as follows:
