While the difficulty of the music can be classified by a variety of standard, conventional methods are classified by the subjective judgment based on the experience of many musicians or conductors. Music score is difficult to evaluate as there is no quantitative criterion to determine the degree of difficulty. In this paper, we propose a new classification method for determining the degree of difficulty of the music. In order to determine the degree of difficulty, we convert the score, which is expressed as a traditional music score, into electronic music sheet. Moreover, we calculate information about the elements needed to play sheet music by distance of notes, tempo, and quantifying the ease of interpretation. Calculating a degree of difficulty of the entire music via the numerical data, we suggest the difficulty evaluation of the score, and show the difficulty of music through experiments.

This paper presents an algorithm for the automatic detection of chord names, scales and tonalities from music file, expressed in MusicXML format which has enough information to determine harmonies vertically like 4-part choir. Chord names are absolute names which can be used and analysed independently of the tonality An algorithm selecting the best chord name is described, which can decide the most appropriate one from ambiguous situations. Candidate musical scales are extracted using the notes in a given time window. The tonalities of the music are determined using the chord names and candidate scales. The final output format of the process is also MusicXML file with chord names, marked non-harmonic notes, relative harmonic symbols and tonalities.

Like any other music, Korean traditional music make a beautiful compound melody of many music instruments. In this paper, we separate melody especially played by two instruments, that is Kayakeum, Piri(Korean pipe) analysing each audio signal. Kayakeum, Piri have a unique frequency component for each sound height. Therefore each melody of them can be expressed into each sheet of notation separately and MIDI codes. We expect that this paper will benefit all the people studying and instructing Korean music.

This study investigated the differences in processing type of working memory between experts and novices when they read music scores. Two experiments were conducted with the articulatory suppression condition. In Experiment 1, eight half notes were shown on the screen for a brief period of time, participants were then requested to write the notes on a music sheet. the stimuli were divided into two: melodious and unmelodious. In similar fashion, Experiment 2 consisted of four-chord sequences, which contained three notes each. The stimuli were also divided into two: harmonious and disharmonious. As an analysis of the results in Experiment 1 & 2, novices commonly showed better performances in the non-articulatory suppression condition than the articulatory suppression condition with both stimuli types. However, experts were relatively affected little by the articulatory suppression with harmonious stimuli. These findings support that while novices entirely depend on the articulatory loop, experts may encode the notes through the visuo-spatial sketchpad before they transfer the information to the phonological store when they are familiar with material.
