Problems solved by technology

In the traditional technology of automatic melody generation, the melody is synthesized after various operations are performed according to the pitch and duration of the note. Due to the single factor consideration, the authenticity of the generated melody is low, which affects the auditory effect.

Abstract

The invention provides a melody generation method and a melody generation device based on a neural network. The method comprises the steps of: acquiring an initial note sequence, preset duration and initial features of the preset duration, wherein duration of a note having the shortest duration in the initial note sequence is less than the preset duration; calculating duration features of each preset duration according to the preset duration, the initial features and a duration neural network model; and calculating the notes according to the calculated duration features of each preset duration, the initial note sequence and a note neural network model, and acquiring a melody according o the calculated notes. Through extracting the features of the melody on different time scales, the structural features of the melody in different duration are considered, melody fragments with good long-range structures are generated through utilizing collaboration of various trained neural network models when generating the melody, the authenticity of the generated melody is improved, and the auditory effect can be ensured.

Description

technical field [0001] The present application relates to the field of deep learning, and in particular, to a method and device for generating a melody based on a neural network. Background technique [0002] Music is an important art form. Usually, music consists of two elements: melody and chords. Among them, melody is a collection distributed along time sequence and is widely considered to be the most important component of music, specifically, melody is a collection of a series of notes distributed along time. Among them, each note contains two elements, pitch and duration. The pitch determines the frequency of the note, and the duration determines how long the note will be played. In the traditional automatic melody generation technology, the melody is synthesized after various operations are performed according to the pitch and duration of the notes. Due to the relatively single factor consideration, the authenticity of the generated melody is low, which affects the a...
