Phrasing: The art of performing music in a way that allows each phrase to be conceived as a single unit. This involves breathing in the correct places, crescendoing and decrescendoing in the correct places, and using rhythm, dynamics, and musicianship to give the music shape. How drum beats are distributed by the player around the drums in context to the song or drum solo. (Free Music Dictionary)
Dynamics: Vocal or singing dynamics is the practice of controlling vocal volume. It goes beyond simply singing loud and quiet. It also includes singing vowels and phrases at the appropriate volume. Dynamics also include silences and rests, which singers shouldn’t forget about. . . . Firstly, let’s start with what it means; the definition of vocal dynamics derives from the Greek word “dynamo”. This translates as “power”. In musical terms, we use define vocal dynamics in singing as being the volume of the voice. This can relate to the variation between notes. (Open Mic)
Vocal Range: The range of notes that a singing voice can encompass. A vocal range of about C above the treble clef to about Middle C is the range of a soprano, the range from F in the top of the treble clef to F below Middle C is the alto range, the range from G above Middle C to C below Middle C would be that of a tenor, and the range of Middle C to C below the bass clef would be the range of a bass. A mezzo soprano (often referred to as simply a “mezzo”) would be between the soprano and alto, a baritone would be between the tenor and bass, and a contralto would be a low alto, or simply an alto. Usually soprano, mezzo soprano, alto and contralto are female voices and tenor, baritone, and bass are male.
Pitch is one of the most fundamental words in all of music. Everything that deals with melody and harmony, scales and chords, starts with pitch. But it is also sometimes misunderstood, and often what we think of as pitch is different to its actual meaning. We might think of a note as sounding “higher” or “lower” than another note, but what does that actually mean? The main property of a sound wave is its frequency, which is just a word for how fast the cycle of the wave is. Pitch is then how the human ear hears and understands that frequency. This is all a bit technical and mathematical, but just know that pitch is basically the frequency of a note. The higher the frequency, the higher the pitch and vice versa, the lower the frequency, the lower the pitch. So, a note sounds “higher” or “lower” than another note if it has a higher or lower frequency than that note. (Hello Music Theory)
Timing / Rhythm: Timing is an important part of singing.  Learning to count the beats, using musical notation and sight reading are all part of the process and will help you to improve your performance  This section aims to provide some basics on timing, rhythm and the art of using your ears!! . . . Rhythm refers to the way in which sounds of varying length and accentuation are grouped into patterns. If you listen to a song the tune itself could not be played on a table but it’s rhythm could be tapped out on one. If you tapped faster or slower the rhythm does not change – only the tempo. You can identify the rhythm by listening to where the accents are placed. Played notes, words, phrases or drum hits are loud, short, long or soft, these are repeated in a measured flow and these are what make up the ‘rhythm’ of the song or musical piece. (Vocalist)
