| 摘要 |
The present invention relates to a method for following a musical score (10) comprising the following steps carried out in real time: recording (23) at least one sound (12) emitted by a performer, estimating (24) at least one chromatic vector (Vx), comparing (26) said chromatic vector (Vx) with theoretical chromatic vectors of said musical score (10), comparing (27) a transition (Tx) between said chromatic vector (Vx) and a previous chromatic vector (Vx-1) with theoretical transitions of said musical score (10), and estimating (28) a work position (Px) of the performer depending on a previous work position (Px-1), from the comparison (26) of said chromatic vector (Vx) and the comparison (27) of said transition (Tx), the recording step (23) being carried out for a suitable period (Di) depending on the ratio between a period (Dx) of said transition (Tx) and a reference period (Dref). |
