This study is intended for both creative and performing musicians and the passionate music lover. A solid prior knowledge of instruments is warmly recommended though. The study encourages awareness of instrumental possibilities that can bring more brilliance and virtuosity to an orchestral approach. The starting point of this book is basic: a simple melody is re-translated again and again into new musical entities of an instrument to instrument combinations. Then "instrumental thinking" is systematically demonstrated: 80 models are derived starting from solo to duo, trio, quartet combinations to ensembles, designed for the woodwinds, brass, harp, percussion and strings. All models are also linked to sampled recordings that can be listened to online via QR codes. The accompanying texts transparently and clearly explain the methods that led to such results. Above all, this study is a thorough preparation to the praxis of orchestration.
