This reduces significatively the storage and time requiered for processing. Presents the advantage that it does not require a training stage, in contrast with the methods based on machine-learning algorithms. The results show a superior performance of the present approach. A comparative study against machine-learning classifiers is presented. Several experiments are carried out for major, minor, augmented, diminished and suspended chords played on acoustic guitar, classic guitar, electric guitar, piano and ukulele. The presence of chords is determined from these metrics. It is important to mention that these statistics are calculated from the combination of notes that form each chord and are automatically grouped as templates. Using the results in the filtering stage, a geometric mean of each chord is calculated. These filters are centered over adjusted frequencies of musical notes in different octaves and the adjustment is accomplished in terms of the detunings on the recording. The algorithm is based on a temporal frequency analysis using Gabor's filter banks. wiki-commons:Special:FilePath/Middle_C_in_four_clefs.In this work, we introduce a template-based computational method to recognize chords through an audio recording of a musical instrument.wiki-commons:Special:FilePath/Middle_C.png.wiki-commons:Special:FilePath/MiddleC-Keyboard.svg.wiki-commons:Special:FilePath/Middle_C.png?width=300.Op een pianoklavier ligt de C telkens voor het groepje van twee zwarte toetsen. Verder is er voor transponerende instrumenten een verschil tussen een genoteerde toon C en de werkelijk klinkende toon.
De actuele toonhoogte van de toon C4 is afhankelijk van de gebruikte stemming en de keuze van de stemtoon A. In de westerse muziek wordt met de do meestal gerefereerd aan de centrale do of C4 (eengestreept octaaf). C, ook do genoemd, is de naam van een van de stamtonen en de grondtoon van de toonladder in C-majeur (Do groot).O dó é a primeira nota da escala diatônica de dó maior, a única que não possui acidentes e portanto é considerada a base do sistema tonal. W enharmonii dźwięki o tej samej wysokości to: his i deses. W szeregu diatonicznym jest to pierwszy dźwięk w każdej oktawie. C (nazwa solmizacyjna: do) – dźwięk, którego częstotliwość dla c¹ wynosi 261,6 Hz.Esta es la única escala mayor que no posee alteraciones y por tanto es considerada la base del sistema tonal. Do en notación latina o C en notación anglosajona, es el nombre de la primera nota musical de la escala diatónica de do mayor.mendean notari izena aldatu zion, errazagoa baitzen solfeoan abestea.

In English the term Do is used interchangeably with C only by adherents of fixed-Do solfège in the movable Do system Do refers to the tonic of the prevailing key. The actual frequency has depended on historical pitch standards, and for transposing instruments a distinction is made between written and sounding or concert pitch.
