流行鋼琴和弦轉位訓練系統

流行鋼琴與古典鋼琴最大不同就是即興演奏能力，流行鋼琴彈奏者通常不使用制式五線譜，主要以和弦搭配不同曲風的節奏，產生曼妙的旋律。流行鋼琴的表現方式通常為伴奏角色，因此和弦與節奏變化的搭配，對流行鋼琴表現而言非常重要。流行鋼琴學習者在彈奏時，其旋律常出現不連貫的情形，其主要原因在於和弦與和弦之間的音程太遠，造成彈奏時的困難。因此，如何協助學習者加強和弦轉位的技巧，為本論文研究方向。本論文對流行鋼琴學習者研發出一套和弦轉位訓練系統，此系統具有三項功能，其一為循序漸進的訓練模式，以滿足不同程度學習者的需求。其二此系統實作本論文所提出的和弦轉位演算法，可依據學習者當下彈奏的和弦，即時在螢幕顯示下一組和弦的適當轉位，進而協助學習者更熟悉和弦的組成及轉位。其三為節奏變化訓練模組，學習者可藉此加強進階學習成效。

The main difference of pop piano and classical piano is the ability of improvisation. Pop piano players often do not read the staff, and mainly play the chord with different genre of rhythm, producing graceful melody. As the pop piano is often played as accompaniment, the collocation of the chord and rhythm is very important. When a learner plays, the melody may sound incoherent. It is because the distance between chords is too far, causing difficulty to play. This thesis thus aims to help learner improve the technique of chord inversion. A chord inversion training system is developed for pop piano learner. The system has three features. The first is the progressive training model to satisfy learners with different levels. Second, this system implements the chord inversion algorithm proposed by this thesis. It can display the next suitable chord inversion on the monitor based on currently played the chord immediately. This thus helps learners be more familiar with the composition and inversion of chords. The third is the rhythm training module, which serves for advanced learning.
