Theory
Sing scales, learn all the modes, not just the classical ones. If you’re looking to expand your range, work those scales. Singing “ah,” (remember to open wide and do it so that you feel like you’re yawning) is the most effective way to run scales because it will force you to open up your throat and expand that range. Try to get just a half a step higher each day. You won’t see immediate improvement here, but if you keep after this every day, you’ll notice that you can easily go up an additional 2-3 whole notes (NOTE: doing this WHILE practicing diaphragm breathing will help you see progress much quicker). Learn some classical pieces, these help you develop a rich tone and well rounded voice. In general, the more classical the style you’re going for, the more careful you’re going to have to be with your voice. That means pushing much more rarely and delicately. In general, you should start singing classical, then layer style on top of your cultivated technique.
Melody A melody (from Greek “singing, chanting”), also tune, voice, or line, is a linear succession of musical tones that the listener perceives as a single entity. In its most literal sense, a melody is a combination of pitch and rhythm, while more figuratively, the term can include successions of other musical elements such as tonal color.
Prosody: It is the study of the patterns of rhythm and sound used in poetry. The patterns of stress and intonation in a language. These contribute to linguistic functions such as intonation, tone, stress, and rhythm. Prosody may reflect various features of the speaker or the utterance: the emotional state of the speaker; the form of the utterance (statement, question, or command); the presence of irony or sarcasm; emphasis, contrast, and focus; or other elements of language that may not be encoded by grammar or by choice of vocabulary. There is no agreed number of prosodic variables. In auditory terms, the major variables are:
Rhythm: e.g. The repeated pattern of stress and unstressed syllables in a sentence
Cadence A unit of pitch variation. In music, a cadence is a melodic or harmonic configuration that creates a sense of resolution. A rhythmical effect in written text. ‘the dry cadences of the essay’ The cadence of someone’s voice is the way their voice gets higher and lower as they speak.
Tone (or Mood) Intonation contrasts with tone, in which pitch variation in some languages distinguishes words, either lexically or grammatically. Tone is the use of pitch in language to distinguish lexical or grammatical meaning, that is, to distinguish or to inflect words. All verbal languages use pitch to express emotional and other paralinguistic information and to convey emphasis, contrast, and other such features in what is called intonation, but not all languages use tones to distinguish words or their inflections, analogously to consonants and vowels. Languages that do have this feature are called tonal languages; the distinctive tone patterns of such a language are sometimes called tonemes, by analogy with phoneme. Tonal languages are extremely common in Africa, East Asia, and Central America, but rare elsewhere in Asia and in Europe; as many as seventy percent of world languages may be tonal.
Stress
Pitch
Tempo: Try to vary it: speak fast, pause, speak slow etc. Pauses are essentially: the best speakers are not those who get the most words out, but whose words get listened to (or processed) the most.
Loudness or Volume
Texture
Timbre (the quality that makes one sound different from another based on sound production): think of same note being played by different instruments
Resonance how the sound vibrates in different cavities: oral, nasal, pharyngeal etc.
