It seems like many songs have the tonality of one key in jazz standards, but there are many cases in which more than one new key could be formed, despite being a short moment. Moreover, some songs contain keys of temporary changes many times in the event that keys are changed transitionally with the sequencing of cords many times, which is called 'Transitional Modulation with Sequences. The proceeding II-V-I of the major and minor keys are used as the sequencing of cords, and the most popular type in this sequencing pattern is the downward modulation in whole-steps or half-steps. The downward modulation in the interval of whole-steps is a useful technique; for example, there should be three compositions in the adjacency circumstances when it is used twice. We could express effectively a phenomenon that feelings go up to the climax and rapidly fall down. The downward modulation in half-steps must be more dramatic because a higher comparative aspect is made between the adjacent two keys.
